HENGJIAN NK22/16 Needle Bearing S8-Z300-16.2-03 (3)
The HENGJIAN NK22/16 needle bearing S8-Z300-16.2-03 (3) is a compact, high-load needle roller bearing designed for the swingarm assembly of the Hengjian S8-Z300 off-road an OEM-type component, it supports the rear suspension pivot with precise guidance and low friction under demanding enduro and off-road use.
Key Features
- OEM-type needle bearing for Hengjian S8-Z300 swingarm section (position 16.2).
- Standard NK22/16 size for easy identification and engineering reference.
- Compact 22 mm bore with high radial load capacity for heavily loaded suspension pivots.
- Machined outer ring and guided needle rollers for accurate running and long service life.
- Open design without seals for flexible lubrication through the swingarm or chassis.
- Steel cage and rolling elements for durability in off-road, wet and muddy environments.

Typical Applications
This NK22/16 needle bearing is primarily specified for the rear swingarm section of the Hengjian S8-Z300 platform, where compact dimensions and high radial load capacity are required.
- Swingarm pivot bearing in the Hengjian S8-Z300 chassis.
- Rear suspension pivot points designed around NK22/16 dimensions.
- Custom motorcycle, ATV or off-road chassis projects using a 22x30x16 mm needle bearing.
- General mechanical assemblies where a high-capacity radial bearing is needed in limited space.
Benefits in the Hengjian S8-Z300 Rear Suspension
When used in the Hengjian S8-Z300 swingarm, the NK22/16 bearing contributes directly to rear suspension precision and durability:
- Reduces friction in the swingarm pivot, supporting smooth suspension movement over small bumps.
- Maintains accurate wheel alignment under heavy braking and acceleration thanks to high radial stiffness.
- Resists impact loads and repeated high-frequency shocks typical of enduro and hard enduro riding.
- Compact design allows a slim swingarm profile and optimized chassis geometry.
Design Notes
As a bearing without inner ring, the NK22/16 type runs directly on a hardened and ground shaft or pivot shaft hardness, surface finish and lubrication help maximize service life and maintain the crisp, precise feeling of the S8-Z300 rear suspension.
