Key Features

Miniature Design: Ultra‑compact profile with fine needle rollers, ideal for space‑constrained mechanisms.
Hex Socket Head: Enables secure mounting and adjustment with a hex key in tight spaces.
Cylindrical Outer Ring: Provides stable contact with flat cam surfaces for smooth rolling.
Caged Needle Rollers: Ensures low‑friction rotation and high load capacity in a small envelope.
Shielded Construction: Prevents contamination ingress and retains pre‑packed grease for maintenance‑free operation.
Pre‑lubricated: Factory‑filled with grease for immediate use; no relubrication port provided.
High‑Carbon Steel: Delivers excellent wear resistance and durability.
