Deep groove ball bearing

Bearing characteristics
NTN deep groove ball bearings have a wide range of applications, with inner and outer raceways forming arc-shaped deep grooves that can withstand radial loads, bidirectional loads, and their combined loads. NTN deep groove ball bearings are also suitable for high-speed rotating applications. In this type of bearing, there are grease filled bearings (double-sided dust cover or double-sided sealing ring bearings), bearings with stop rings, etc. The use of these NTN bearings can simplify the design of the bearing housing.
Bearing type
Dust cover, non-contact ZZ: steel plate cover on the outer ring; There is a V-shaped sealing groove on the inner ring and it maintains a certain gap with the dust cover.
Sealing ring, non-contact LLB: The iron core synthetic rubber sealing ring is installed on the outer ring; Align the other end of the sealing ring with the V-shaped sealing groove on the inner ring, and maintain a certain gap between the surface of the sealing groove and 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 sealing ring with the V-shaped sealing groove on the inner ring. The surface of the sealing groove is in contact with the sealing ring.
Sealing ring, low torque LLH: The basic structure is similar to the LU type, but the lip end of the sealing ring is specially designed to prevent dust and reduce bearing torque.
