Steel Cartridge / Deep-Groove Ball Bearings

Steel cartridge/deep-groove ball bearings from Strummer are designed for high durability and fast rotation. Our bearings have been widely used in the world of road biking and mountain biking (MTB), which in fact 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.

Strummer Bearings use rubber seals (rubber covers) made from NBR (Nitrile Butadiene Rubber) to prevent water and dust from entering. The precision material cage evenly separates each ball, allowing for 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 (Unitary State of the Republic of Indonesia).
