The bearing is made of chrome steel for durability and resistance to deformity under heavy loads, and it has metal shields on both sides of the bearing to keep lubricant in and contaminants out. It comes pre-lubricated from the manufacturer so that no additional lubrication is required. This deep-groove shielded ball bearing is suitable for use in applications that involve combined radial and axial loads, and a need for high running accuracy at high rotational speeds. Such applications include clutches, drives, gearboxes, compressors, pumps, turbines, and printing and textile machines, among others.\u003cbr\u003e\u003cbr\u003eRolling bearings use rolling elements to maintain the separation between moving parts to reduce rotational friction and support radial and axial loads. These elements can be one of the following types: ball, cylindrical, spherical, barrel, needle, spindle, or tapered. All rolling bearings are open, shielded, or sealed. Sealed bearings are lubricated with oil or grease in the bearing factory, while open and shielded bearings are meant to be lubricated in place, with periodic reapplication of lubrication, based on use. The shield protects the working parts of the bearing from environmental debris that may be introduced and could reduce the ball bearing speed and lifespan. Rolling bearings are used in a range of applications from agricultural machinery to conveying equipment, robotics, dental equipment, elevators, rolling mills, ship rudder shafts, and aggregate crushers, among others.\u003cbr\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003ch4\u003eUsed with the followings Keiser bikes and ellipticals:\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eSchwinn AC Performance Plus\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eStar Indoor Cycle and Spin Bikes\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Keiser Fitness","offers":[{"title":"Default Title","offer_id":42234047201515,"sku":"6000ZZ","price":13.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2063\/2201\/products\/6000ZZ.jpg?v=1640271422"},{"product_id":"keiser-m3-m3-m3i-replacement-sa-hub-flywheel-550808","title":"Keiser M3, M3+, M3i, Replacement SA - Hub-Flywheel - 550808","description":"\u003cp\u003eKeiser M3, M3+, M3i, Replacement SA - Hub-Flywheel - 550808\u003c\/p\u003e\n\u003cp\u003eDirect from Keiser replacement parts - Pre-Owned and New\u003c\/p\u003e\n\u003cp\u003eFits All Keiser M3, M3+, M3i\u003c\/p\u003e\n\u003cp\u003ePre-owned is tested and in excellent working condition.
