Electric motor bearings or motor bearings, are a special type of bearing used in electric motors or motors. The most common type is rolling bearings. The motor bearing used in the motor is a part that supports the shaft. It can guide the rotation of the shaft and also bear the idling parts on the shaft. In the motor, the bearing is also used to connect the motor parts together, allowing the transfer of any force and movement, and is […]

Mechanical properties of stainless steel bearing materials and ordinary bearing materials. Stainless steel bearings include: 440C, 420,304, 316 and 316 material, to compare with Chrome Steel bearings, we need to put aside the rust-proof ability of the bearing, because ordinary bearings basically have no anti-rust ability, so we have to consider the mechanical properties of stainless steel bearings. From the perspective of solving corrosion problems, let’s make a basic summary of stainless steel bearings. The carbon content of stainless steel […]

The construction of the R series enables these bearings to take a radial and axial load. The well designed ball complement and selection of retainer permit use of this series in speed motor applications. This series is produced open, shielded or sealed. Sealed bearings are made slightly wider than open type. FREE SAMPLES are available for all of our R bearings with shipping cost at customer side. CUSTOMIZATION is welcome on all of our R bearings, contact us today to […]

Thrust ball bearing is separable in 3 parts, they are shaft washer, housing washer and steel balls with cage. Thrust ball bearings can be applied to high axial load and low medium speed, they cannot take radial load. We have both FM series (raceway with groove) and F series (raceway without groove) available for your choices. And both Chrome steel 52100(Gcr15) and stainless steel miniature thrust ball bearings are manufactured in our factories. FREE SAMPLES are available for all of […]

Introduction to Miniature Bearings Miniature bearings in the metric series with an outer diameter less than 9mm, and in the Inch series with an outer diameter less than 9.525mm. The main materials include carbon steel, chrome steel, stainless steel, plastic, ceramics, etc. The minimum I.D. can be 0.6mm, and generally the I.D. is 1mm. Product Features In miniature bearings with ultra-small bore sizes, the miniature deep groove ball bearings include metric 68 series, 69 series, 60 series, etc., and inch […]

Ball bearings are simple but powerful components that minimize friction in rotational applications ranging from industrial machinery to office equipment. Spherical ball bearings have only minimal contact with their containing races, allowing them to transfer radial or axial loads with rapid, fluid motion. A variety of housing shapes and lubrication options improve versatility while promoting performance across a long working life. Miniature Bearings Miniature bearings are defined by their very small rolling elements, with bore diameters no larger than 10 […]

The top 10 bearing suppliers in the world in 2023 are SKF Sweden, INA Germany, FAG Germany, NSK Japan Ltd, TIMKEN USA INC, NACHI Corporation, NTN Japan Corporation, NMB Japan, KOYO Japan, and TORRINGTON USA. They account for about 75% of the market, with Chinese companies making up the remaining 20% and the remaining 9%. Japan has five of the top ten bearing enterprises, followed by Sweden with one, Germany with two, and the United States with two. Japan is […]

Fitrun’s many models of miniature ball bearings have a potential interchange with NMB bearings. You will find the interchange information in the NMB Bearing Cross Reference Charts in this article. All the models listed in the charts are stainless steel ball bearings, they are also available in chrome steel which is relatively cost effective for lower requirement applications.

Headquartered in Gothenburg, Sweden, SKF Group is a leader in bearing technology and manufacturing. Sven Wingquist invented the double row self-aligning ball bearing in 1905, and then founded the Svenska Kullargerfabriken Swedish Ball Bearing Manufacturing Company in 1907, referred to as SKF.

The bearings can be divided into two types according to the different friction properties during the movement process, one is rolling bearings, and the other is sliding bearings. Rolling bearings and sliding bearings are big categories. There are dozens of types of bearings in small category. Here in the following contents, we present you the 13 types of bearings and their main applications.
