Enduro Bearings are quality bearings manufactured specifically for cycling - certain applications require specific materials, greases, and sealing arrangements. Enduro has it covered for environments and disciplines.
Material: Chromium Steel GCR15 (Race & Balls) Grease: SINOPEC HTHS Bearing Grease or equivalent, 30% filled Seal: 2RS (2RS = 2 Rubber Seals) Precision: ABEC 3 Quality Level: EMQ Ball Roundness: Grade 10
This listing is for single bearings, and not pairs.
All Bearing sizes are stated above in the drop down menu in following order: Inner Diameter x Outer Diameter x Depth/thickness in mm (unless mentioned otherwise)
High quality chromium steel replacement wheel bearings. Note, the images for each bearing are for reference only for stock at time of taking picture. The actual bearing supplied may differ in seal colour to that shown, but will always be of same specification to that listed above.
All Bearings will be supplied to a minimum of ABEC-3 standard (note the cycle trade usually fit ABEC-1 at original equipment OE level). The ABEC rating for bearings commences at ABEC 1 which is seen in most bearing applications for bicycles supplied from the factory. Higher end bearings for bikes are ABEC 3 or even ABEC 5 for very expensive precision hubs for instance. We at Kinetic supply ABEC 3 rated bearings - If you are looking at a competitors product that doesn't mention it's ABEC rating, it could be safe to assume it is not rated or only supplied to ABEC 1 standard. The term 'EMQ' is the overall specification which encompasses all aspects of the bearing, and not just ABEC precision. The abbreviation EMQ stands for Electric Motor Quality - this was a standard derived from the electric motor industry as a minimum requirement of standards to cover all aspects of the bearing to ensure quality. (i.e the grade of rubber used in the seal, a high grade of race/ring material, grease type and grease fill etc). The electric motor industry dictate very high standards due to the extreme conditions they operate in, and was a way of ensuring that inferior/cheaper quality bearings weren't used. margin-top: 32pt;
2RS = 2 Rubber Seals (1 rubber seal each side). If your bearing says RS on the seal, it is saying this is a Rubber Seal, so if there are 2 seals in total (1 each side), you require 2RS.
Please rest assured you are buying quality, tried and tested bearings for bicycle application. We have been supplying the cycle trade directly for a number of years now, and have experience with supplying the correct type of bearing for the correct application. For instance, other sellers/suppliers will happily sell you wheel bearings for your mountain bike frame and vice versa. We will not, as experience tells us they will not last as long.
Ensure you use appropriate tools to fit the bearings and that the seating surface is clean and free from rough edges so that they fit true and square. Quite often bearings can feel fine before fitting, but then feel "notchy" or "rough" after fitting. This is almost always due to the bearings not sitting square and true. To prolong the life of your bearings, do not direct a high jet of water near areas of your bike where bearings are situated - an ingress of water can lead to premature bearing failure. It's also a good idea to swipe a smear of good quality grease on the outside facing seal after installation - this will help keep the dreaded moisture at bay a bit longer. We recommend a thick water resistant grease such as Mobil XHP222 on the outside of all bearings to keep moisture away. Note this grease can also be used internally on non-fully revolving bearings such as headsets and mountain bike frame pivots (it's too thick for bearing internals of wheels and BB's generally).
Also, don't be tempted to fit a frame bearing to a bottom bracket/wheel or vice versa - we usually supply MAX bearings for frames (they do not contain as much grease but are super strong which is important as they do not fully revolve). Wheel & Bottom Bracket Bearings have an internal cage and gaps between balls to aid grease fill and heat dissipation.
