Airframe Roller Bearing – MS27645‑4 (KSP4), Self‑Aligning Heavy‑Duty Bearing
Airframe Roller Bearing – MS27645‑4 (KSP4), Self‑Aligning Heavy‑Duty Bearing
Introducing the MS27645‑4 roller bearing, also known as KSP4 — a rugged, self-aligning, airframe ball bearing tailored for high-reliability control systems. Designed with precision per airframe standards, this bearing is sealed, pre-lubricated for life, and exudes long-lasting performance even in demanding environments.
Key Features & Benefits:
- Self-Aligning Design: Accommodates up to ±10° misalignment for smoother motion under load
- Sealed & Pre-Lubricated: Comes fitted with bonded PTFE seals and MIL-G-81322-grade grease for maintenance-free operation.
- Corrosion-Resistant Construction: Cadmium plating and heat-treated chrome steel ensure toughness and longevity.
- Aerospace-Grade Specs: Engineered for maximum reliability in airframe applications—ball, ring, and seal materials adhere to strict aerospace standards.
Technical Specifications:
- Bore (d): 0.2500″
- Outer Diameter (D): 0.9014″
- Inner Ring Width (W): 0.4840″
- Outer Ring Width (H): 0.3350″
- Load Rating: Radial ≈ 1,410 lbf; Thrust ≈ 300 lbf
- Self-Alignment: Internal; ±10° adjustment capability.
- Construction: Self-aligning, double-row ball bearing, cadmium-plated, heat-treated to Rockwell C60-66 with aerospace-grade tolerances.
- Lubrication: Pre-lubricated with MIL‑G‑81322 grease
- Condition: New, fully traceable to original manufacturing
