Product features of ZYS deep groove ball bearing:

Bearing inner and outer ring: The inner ring, outer ring and rolling elements of the bearing form an organic rotating unit. The inner and outer rings of ZYS deep groove ball bearings are made of GCr15 high-quality steel. The steel has high density and good ductility, which effectively prolongs the service life of the bearing.

Bearing rolling elements: The rolling elements transfer the load between the inner ring and the outer ring. ZYS deep groove ball bearings use G10 national standard steel balls to ensure stable operation and low noise.

Bearing cage: The bearing cage can reduce the frictional heat, optimize the load, keep the rolling elements in the correct position and interval, and prevent the rolling elements from falling off during installation. ZYS deep groove ball bearings use steel stamping cage or brass solid cage.

Bearing seal:

ZYS can provide deep groove ball bearings with different sealing structures, including open type (No shields), ZZ type (Metal shields), 2RS type (Contact rubber seals), 2RZ type (Non-contact rubber shields).

RS type (Contact rubber seals): The rubber seal material can effectively prevent foreign matter (liquid state) and impurities from intruding into the bearing and causing internal damage to the bearing. It has a good mute effect and is suitable for harsh environments.

ZZ type (Metal shields): The sealing material is stainless steel, which can effectively prevent external impurities from invading the bearing and causing internal damage to the bearing. It has low friction resistance, fast heat dissipation, high temperature resistance, high speed, and it is suitable for relatively clean working conditions.

Open type (No shields): The steel ball can be seen directly without a seal, which is suitable for a sealed environment such as a gear box and an environment with a lot of oil. The friction resistance is small, the idling effect is good, and the speed is super high.

Bearing clearance:

The radial clearance of rolling bearings is divided into five groups: C2 group, CO group, C3 group, C4 group and C5 group. The clearance value is from small to large. Among them, the C0 group is the standard clearance, which is suitable for general operating conditions, general temperature and common interference fit. Bearings with poor rigidity or working under conditions of high temperature, high speed, low noise and low friction should choose a large radial clearance. The original internal clearance is usually greater than the operating clearance. This is due to the difference in the degree of fit in the installation and the difference in the thermal expansion of the inner and outer rings and related parts of the bearing, which causes the inner and outer rings to expand or contract.

Bearing lubrication:

1. The purpose of rolling bearing lubrication is to form a thin oil film between the rolling surface and sliding surface of the bearing to prevent direct contact between metal and metal.

2. The grease sealing device is simple in design and does not require special oil supply equipment. It can prevent the intrusion of dust and moisture. Maintenance is simple, long-term operation does not need to be replaced, it is the most used lubricant for rolling bearings. Grease lubrication runs for a long time without replacement, and is the most used lubricant for rolling bearings.

3. Grease filling varies with bearing, bearing housing design, space volume, rotation speed and grease type. The amount of grease filled in the bearing should be 20%-30% of the inner space of the bearing. It should be reduced to 20% at high speed.

4. ZYS has added the necessary amount of grease in accordance with the process standard, and can meet the use under normal working conditions, so the user does not need to add additional grease.

Advantages of ZYS deep groove ball bearings:

1.Low noise: ZYS adopts advanced silent manufacturing technology to produce energy-saving and environmentally-friendly high performance bearings, featuring low noise, low torque, low temperature rise, high limit speed, and low friction.

2.High precision: ZYS adopts new materials and special structure design, and uses high-efficiency polishing technology, so that ZYS bearing product has the characteristics of good sealing, low running resistance, and high rotation accuracy.

3. Long life: ZYS adopts hot rolling technology and special heat treatment process to improve the bearing's high temperature resistance, wear resistance, impact resistance, high load capacity and other properties, and enhance the reliability and service life of the bearing.

MOTORCYCLE

Each motorcycle is usually equipped with 20 to 30 bearings. These bearings are used for important rotating parts such as engines, transmissions, and wheels to support driving, and are responsible for reducing friction and driving the engine power to the wheels. Therefore, the performance required for motorcycle bearings is to achieve smooth rotation through low friction, low vibration and high durability. These performance affect the fuel consumption and safety that are closely related to our life. ZYS always pays attention to these details and strives to develop bearing and optimize the bearing design to improve the quality of life and protect the global environment.

ELECTRIC MOTOR

Motors are used as power sources in all industries. In the development of the electrification of power sources, in order to meet the requirements of environmental protection, low energy loss and high reliability, ZYS continuously developed high-performance bearings with low friction. These bearings are widely used in the rotating part of the motor, which can play a significant role in bearing the load carried by the motor while supporting smooth and quiet rotation.

METALLURGY AND CONSTRUCTION

There are many kinds of metallurgical equipment, including not only the equipment needed by the raw material factory, but also the equipment needed from the upstream process to the downstream process, such as steelmaking process, steel rolling process and leveling process. These bearings are used under the special conditions of iron powder, water and heat of metallurgical equipment, so they need to meet the requirements of heavy load , vibration shock, from ultra-low speed to high-speed & rapid acceleration and deceleration. "Stable operation and improved production efficiency" can be described as a representative industry in the field of metallurgical equipment. ZYS is not only in bearing design technology, but also in various aspects such as bearing material technology, lubrication technology, and analytical technology.

WIND ENERGY

As a renewable and clean energy source, wind power is rapidly developing all over the world. Large wind turbines are giant machinery. Nowadays, many 2MW wind power plants under construction have wind turbine blades with a length of about 40 meters, a rotating shaft with a height of 60 to 100 meters and total weight of more than 200 tons. Therefore, the bearings used in wind power must also be large, with an inner diameter ranging from 100 mm to 700 mm. Some models require bearings with an inner diameter of nearly 2 meters. Bearings for wind turbines require high reliability, because the bearings are designed to keep the windmill running for 20 years; and when the fault occurs, the parts are not easy to replace (the bearing is used at a long distance from the ground). Bearing manufacturers need to have a high degree of computer analysis technology and exquisite skills in materials and heat treatment, and need to master the test evaluation technology for large bearing .
