28TAG12 Cased Single Direction Thrust Ball Bearing 28x51.8x16mm Forklift Auto

1. Product Overview

28TAG12 is pre-assembled integral shell single-direction thrust ball bearing, standard overall dimension 28mm inner bore × 51.8mm outer diameter × 16mm total thickness.
Model Code Explanation:

• TAG: Integrated cased thrust ball bearing assembly, complete unit including outer protective shell, two quenched thrust washers, precision steel balls and stamped steel cage, shipped as one whole part without separate assembly matching
• 28: Nominal matching shaft inner bore size 28mm; 12 stands for standard thickness series of automotive clutch thrust bearing

Spherical steel balls act as rolling elements, matched with double flat race washers with circular ball raceways. This bearing only bears pure unidirectional axial thrust load, cannot carry radial force. The integrated stamped outer shell forms passive dust barrier to block dry dust and metal debris in workshop environment. Factory pre-filled long-life anti-wear lithium grease inside closed inner cavity, realizing long-term maintenance-free medium-speed operation. Widely applied to forklift clutch separation assemblies, light truck steering kingpin axial positioning, agricultural tractor power clutch, small construction machinery hydraulic clutch and other vehicle transmission components requiring compact unidirectional thrust support.

2. Technical Specifications

Mounting dimension drawings, forklift clutch assembly matching guides and axial thrust impact durability test reports can be provided on customer request.

3. Core Advantages

1. All-in-one TAG shell integrated structure, outer shell, thrust washers, steel balls and cage fully pre-assembled, direct press-fit installation without extra component pairing, greatly improve mass production assembly efficiency.
2. Spherical steel ball rolling elements deliver ultra-low rotation friction torque, realize smooth clutch separation and flexible steering rotation, effectively reduce operation noise and shaft surface abrasion.
3. Compact thin flat cross-section design, occupies minimal axial installation space inside clutch housings and steering knuckles, meets lightweight layout requirements of forklift and light commercial vehicle machinery.
4. Superfinishing circular ball raceway on both thrust washers, uniform contact stress of steel balls, excellent anti-fatigue performance under frequent alternating clutch impact thrust load.
5. Integrated outer stamped shell provides passive dust shielding effect, block farm dust, workshop fine metal powder and impurities from invading internal ball raceway, extend service life under harsh working conditions.
6. Standard unified interchangeable industry dimensions, fully compatible with global mainstream 28TAG12 clutch thrust ball bearings, direct replacement without modifying vehicle housing and shaft structural size.
7. Sealed inner cavity with factory pre-filled anti-wear grease, effectively avoid grease leakage during long-term vibration operation, realize maintenance-free daily use.
8. Rich customizable options: C3 enlarged axial clearance group, reinforced double lip dust shield upgrade, AISI304 stainless steel anti-corrosion variant, OEM laser marking on outer shell, neutral export anti-rust carton packaging, high-temperature extreme pressure grease pre-filling.
