Bearing characteristics
NTN deep groove ball bearing is widely used. Its inner and outer ring raceways are in arc deep groove, which can bear radial load, two-way load and its resultant load. NTN deep groove ball bearings are also suitable for high-speed rotating applications. Among these bearings, there are grease filled bearings (double-side dust cover or double-side seal ring bearings) filled with lubricating grease, bearings with stop rings, etc. The use of these NTN bearings simplifies the design of the bearing housings.

Bearing type
Dust cover, non-contact ZZ: steel plate covers the outer ring; The inner ring has a V-shaped sealing groove and maintains a certain clearance with the dust cover.
Sealing ring, non-contact LLB: the iron core synthetic rubber sealing ring is installed on the outer ring; The other end of the sealing ring shall be aligned with the V-shaped sealing groove of the inner ring, and the surface of the sealing groove shall have a certain clearance with the sealing ring.
Sealing ring, contact type LLU: the iron core synthetic rubber sealing ring is installed on the outer circle; Align the other end of the seal ring with the V-shaped seal groove of the inner ring. The surface of the seal groove is in contact with the seal ring.
Sealing ring, low torque type LLH: basic construction similar to LU type, but the lip of the sealing ring is specially designed for dust prevention and reduced bearing torque.
