Thin Section Bearings are mainly lubricated with grease, and the grease is added at the factory according to a fixed ratio.The grease base components and thickener ratios are uniform, making it suitable for the internal operating space of the bearing.The amount of grease filler should be 30% to 50% of the bearing's internal cavity volume. This ratio balances lubrication effect and rotational resistance.The grease adheres evenly to the contact area of the rolling elements and raceways, continuously forming an oil film.The sealed structure reduces grease loss, eliminating the need for frequent grease replenishment under normal operating conditions.For special operating conditions, the grease formula and filling ratio can be adjusted. For special operating conditions, the grease formula and filling ratio can be adjusted. For high-speed and high-temperature models, a suitable special grease will be selected.

The mainstream precision grades for thin Section Bearings are P4 and P5.The inner diameter, outer diameter, and width tolerances of P5 grade bearings are within the normal range, and the raceway form and position deviations, radial and axial run-outs meet general usage requirements.P4 grade is a high-precision specification with narrower dimensional tolerances, higher raceway geometric accuracy, and significantly reduced radial and axial run-out.The two grades of parameters are clearly defined, and all accuracy indicators are implemented in accordance with the specifications, ensuring a high degree of uniformity in the accuracy performance of bearings of the same grade.

Thin Section Bearings provide a uniform load distribution during dynamic operation, making them suitable for medium- and high-speed, medium- and small-scale alternating load conditions.P4 and P5 levels correspond to different rotational runout limits, and the vibration amplitude is controllable during high-speed operation.The rolling elements and raceways maintain stable contact, resulting in low frictional loss and a gradual temperature rise during continuous operation.The internal lubricating film can be maintained intact under dynamic pressure, effectively preventing dry friction.There are no obvious shocks or abnormal noises during start-up, shutdown, and speed change. The dynamic response is stable and it can maintain operating accuracy for a long time, making it suitable for various transmission mechanisms for continuous operation.
