Description
CEMA Headset Bearing 41.8 x 30.5 x 7.7 mm 45°/45°
The CEMA Headset Bearing 41.8 x 30.5 x 7.7 mm 45°/45° is a high-quality bicycle headset bearing designed to replace a worn, loose, or noisy bearing. The headset bearing is an important part of the bike's handling, as it enables the fork and handlebars to move smoothly, evenly, and without play.
This bearing is suitable for headset solutions requiring a size of 41.8 mm outer diameter, 30.5 mm inner diameter, and 7.7 mm height. The contact angles are 45°/45°, so compatibility must also be checked for the angles, not just the diameters. The wrong contact angle can cause a poor fit, loose steering, creaking, or premature bearing wear.
The CEMA headset bearing is a good replacement part for road, gravel, and mountain bikes when the old bearing is worn or the steering no longer feels smooth. The bearing should be replaced if the steering feels notched, creaks, is stiff, or has play.
CEMA 41.8 x 30.5 x 7.7 mm headset bearing - technical specifications and compatibility
Dimensions are crucial when choosing a headset bearing. This bearing is not the same as 41.8 x 30.1 x 6.5 mm, 41.8 x 30.5 x 8 mm, or 41.8 x 32.7 x 6 mm bearings, even though the outer diameter is almost the same. Check the markings on the old bearing or measure the bearing before ordering.
A 45°/45° contact angle means that both the inner and outer races have a 45-degree angle. This is a common angled ACB headset bearing, but it should not be replaced with a 36°/45° bearing unless specifically approved by the frame or headset manufacturer.
