Steel Cartridge/Deep-Groove Ball Bearings

Strummer's steel cartridge/deep-groove ball bearings are designed for high durability and fast rotation. Our bearings have been widely used in the world of road bikes and mountain biking (MTB), which are known to require high performance. Strummer is one of the best choices in its class because of its fast, smooth and consistent rotation, even when facing difficult, dirty and wet terrain.

Bearing Strummer uses rubber seals made of NBR (Nitrile Butadiene Rubber) to prevent water and dust from entering. The cage made of precision material evenly separates each ball, allowing smooth rotation during use. We use steel balls with ABEC-3 standards to achieve a balance between precision, speed, and durability.

Note: Strummer is a distributor of bearings with the OXO and Laker brands in the Republic of Indonesia (NKRI).
