Roller Bearing – FAA-Traceable Aircraft Bearing | MS27645-6A (KSP6A)
Roller Bearing – MS27645‑6A (KSP6A) | FAA‑Traceable
The MS27645‑6A Roller Bearing, also known as KSP6A, is a fully traceable, self-aligning radial ball bearing built to MIL‑MS specifications. Commonly used in airframe control systems, this bearing meets the demands of high-performance aviation applications. Its compact design, cadmium plating, and PTFE contact seals make it ideal for reliable operation under thermal and mechanical stress.
Key Features
- Self-aligning radial ball bearing with ±8° misalignment capability
- Meets MIL‑MS specification MS27645‑6A; equivalent to KSP6A
- Dual bonded PTFE contact seals; pre-lubricated and maintenance-free
- Heat-treated rings and balls (Rockwell C 60–66) for high-load tolerance
- Cadmium-plated exterior per QQ‑P‑416 Type 1 Class 2 (excludes bore/seals)
- Fully traceable with manufacturer certification included
Specifications
- Bore Diameter: 0.3747–0.3750 in
- Outer Diameter: 0.8746–0.8750 in
- Inner Ring Width: 0.3105–0.3130 in
- Outer Ring Width: 0.2450–0.2500 in
- Load Direction: Radial
- Self-Alignment Angle: ±8°
- Weight: Approx. 0.03 lb
