What’s the characteristics and types of NTN groove ball bearing?

694 Published by admin1 Oct 11,2018

NTN groove ball bearing have the widest application range, and the inner and outer ring raceways are arc-shaped deep grooves, which can withstand radial loads, two-way loads, and their combined loads.

Bearing characteristics of NTN groove ball bearing
NTN groove ball bearing have the widest application range, and the inner and outer ring raceways are arc-shaped deep grooves, which can withstand radial loads, two-way loads, and their combined loads. NTN deep groove ball bearings are also suitable for high speed rotating applications. Among these bearings, there are grease-filled grease bearings (double-sided dust caps or double-sided seal bearings), with snap ring bearings. The use of these NTN bearings simplifies the design of the bearing housing.

Bearing type of NTN groove ball bearing
Dust cover, non-contact type ZZ: The steel plate is covered by the outer ring; the inner ring has a V-shaped sealing groove and maintains a certain gap with the dust cover.
Sealing ring, non-contact LLB: iron core synthetic rubber sealing ring is mounted on the outer ring; the other end of the sealing ring is aligned with the V-shaped sealing groove of the inner ring, and the surface of the sealing groove and the sealing ring have a certain gap.
Sealing ring, contact LLU: The iron core synthetic rubber sealing ring is mounted on the outer circle; the other end of the sealing ring is aligned with the V-shaped sealing groove of the inner ring. The surface of the sealing groove is in contact with the sealing ring.
Sealing ring, low torque type 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.

Others of NTN groove ball bearing
With snap ring bearings, some bearings have a snap ring on the outer ring that secures the axial position of the bearing and simplifies the design of the bearing housing.
The expansion-compensated deep groove ball bearing has the same main dimensions as the ordinary bearing, and the outer ring outer diameter surface is provided with an annular groove, and the groove is provided with a high-mole material having a large expansion coefficient.
Long life bearing (TMB/TAB bearing): The size of the long life bearing is the same as that of the standard deep groove ball bearing, but the bearing is subjected to special heat treatment to prolong the bearing fatigue life and wear life.

AC bearings (bearings that prevent creep): AC bearings are the same size as standard bearings, but with an extra two O-rings on the outer ring. This bearing can be used in steel bearing housings to withstand the outer ring with load rotation; it is suitable for environments where creep is not allowed and tight fit is not possible.
