The maintenance free ball bearing unit is sealed with high-quality lithium grease suitable for sealing bearings, which can be used for a long time. The bearing is equipped with a sealing device with excellent sealing performance, which not only prevents the leakage of lubricating grease but also prevents impurities, dust, and water from entering the bearing.

When the bearing rotates, the lubricating grease inside the seal runs with the shaft internally, causing the lubricating grease inside to lift.

Adequate and effective lubrication can be provided without the need for lubricating grease for a long time.

(1) Pre sealed with a certain amount of lubricating grease, users do not need to add lubricating grease before use, which can reduce their maintenance workload and lower maintenance costs.

(2) Equipment such as oil pipes that do not require lubricating grease can make the equipment more compact.

(3) Sealing can prevent grease leakage and environmental pollution.
