6200 series deep groove ball bearing

ZYS 6200 Series bearings have deep and honed raceways and are widely used in the applications which need to carry both radial and axial loads. 6200 Series bearings have four available types: OPEN type (No shields), ZZ type (Metal shields), 2RS type (Contact rubber seals), 2RZ (Non-contact rubber seals).

Application of ZYS 6200 Series bearings: Household appliances, Agricultural machinery, Motor, Power tools, Textile machinery, Printing Machinery, Automotive applications, Washing machines motors, Clutch bearings.


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.
