HENGJIAN brake arm bearing 6000RS S7-Z300-22.2-3B (3B)
The HENGJIAN brake arm bearing 6000RS S7-Z300-22.2-3B (3B) is a compact deep groove ball bearing designed for the brake arm assembly of Hengjian Z300 platform an original-type replacement component, it supports smooth, precise rotation of the brake arm pivot, helping maintain consistent braking feel and reducing friction and wear in the linkage.
Main features
- Deep groove ball bearing in 6000RS size for compact brake arm pivots.
- Approximate dimensions 10 × 26 × 8 mm (inner diameter × outer diameter × width).
- Rubber-sealed design to protect the rolling elements from dust, moisture and road contamination.
- Suitable for high rotational speeds typical of brake arm and pedal pivots.
- Optimized for the HENGJIAN S7-Z300-22.2 brake arm assembly on Z300 series motorcycles.
- Steel construction for durability under repeated braking loads.

Typical applications
The brake arm bearing 6000RS S7-Z300-22.2-3B (3B) is specifically associated with the brake arm system of Hengjian Z300 series this assembly it supports rotational movement at the brake arm pivot, ensuring predictable braking response and stable lever or pedal travel.
- Brake arm pivot bearing in the rear brake assembly on Hengjian Z300 platform motorcycles.
- Support bearing for linkage components where a 6000RS-sized sealed bearing is specified.
- Replacement for worn or noisy original brake arm bearings in the same assembly.
Benefits in use
- Helps maintain precise brake modulation and consistent pedal or lever feel by minimizing play at the pivot.
- Deep groove design and quality steel raceways provide smooth rotation under combined radial and light axial loads.
- Rubber seal helps keep grease inside the bearing and contaminants outside, extending service life.
- Compact 10 × 26 × 8 mm format integrates neatly in tight brake arm housings.
- Original-style specification supports reliable long-term performance in demanding off-road and street conditions.
