87500 Felt Seal Ball Bearing

Key Features

87500 is a Felt Sealed Single Row Ball Bearing with an extended inner ring and comes pre-lubricated with Grease allowing for use upon delivery. Felt Seals are designed to prevent dirt and other contaminants from entering the bearing while retaining the lubricant inside which extends its bearing life and maintains its performance capabilities.

Applications / Industries

87500 Felt Seal Bearings are used in a range of applications from Construction Machines, Agricultural Equipment, Gardening Equipment, Engines, Transmissions, Transfer Case, Power Steering, among others. 

This 87500 ball bearing is a high-precision premium quality deep groove 10*30*9mm ball bearing made to ABEC 3 precision standards from AXIS. This bearing features a seal on one side and a shield on the other along with an extended inner race. What sets this 87500 bearing apart from others is the ABEC 3 precision standard that this bearing is made to, the grade 10-balls used, and the superb electric motor quality rating (EMQ). ABEC 3 means that the bearing has a micron deviation from a nominal of 20.000mm of -8 micrometres. The standard ABEC 1 precision standard that almost all ball bearings are made to today has a deviation of -10 micrometres. In simple terms, the more precision a bearing is, the better it will perform in any given application. The grade 10 balls within this bearing are typically only found within ABEC 5 or higher bearings because of their more true roundness and precision. The balls within a bearing share the load capacity, which also increases the working life versus the standard grade 25 balls used in other brands. The electric motor quality rating means that the bearing must operate at an extremely low noise level with minimal to no vibration. To achieve this, the 87500 bearing features raceways that are precision honed to a superb finish.

More specifically, 87500 ball bearings are also commonly known as felt series bearings because manufactures use to use felt seals in this bearing type, however, the new standard is to use rubber for the seal material. 87500 bearings are found in a wide range of industrial, automation, and electric motor applications. They are designed to reduce rotational friction and support loads. The load is spread evenly across the grade 10 balls and as the inner bearing race rotates so do the balls.
