Steel Cartridge / Deep-Groove Ball Bearings

The steel cartridge/deep-groove ball bearing from Strummer is designed to have high durability and fast rotation. Our bearings have been widely used in the world of road biking and mountain biking (MTB), which notably require high performance. Strummer has become one of the best choices in its class due to its fast, smooth, and consistent rotation, even when facing difficult, dirty, and wet terrain.

Strummer bearings use a rubber seal made of NBR (Nitrile Butadiene Rubber) to prevent water and dust from entering. The cage made from precision material 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 brands OXO and Laker in the Unitary State of the Republic of Indonesia.
