LM78349 Tapered Roller Bearing-manufacture,factory,supplier from China

How to install tapered roller bearingsAdjusting the axial clearance for the installation of tapered roller bearings can be achieved by adjusting the nuts, washers, and threads in the bearing seat holes on the shaft neck, or by using methods such as pre tensioning springs.

1、 This type of bearing can withstand both radial and axial loads and consists of two outer rings, one spacer ring, and one inner sleeve component. The manufacturing clearance of bearings has been adjusted with spacers according to the user's working conditions and national standards when the product leaves the factory.

Schaeffler Technologies AG recently submitted a patent application titled "An Improved Cylindrical Roller Bearing and Its Retaining Structure", with publication number CN 119641798 A. The application was submitted in September 2023.This new patent proposes an innovative design scheme for cylindrical roller bearings, with a focus on the unique structure of its cage. The cage is composed of multiple beams evenly distributed along the circumference, each beam equipped with an axially extending inclined surface.

1、 Single row tapered roller bearingsThe inner and outer rings can be installed separately;Rear wheels that can be used for drum brakes (such as Santana rear wheels);Has higher load-bearing capacity and relatively lower rotational speed;Small installation space, easy to install;2、 First generation wheel hub bearingsFixed and pre-set bearing clearance;Lifetime lubrication, maintenance free;Permanent sealing;Sealing rings are divided into rubber oil rings and combination oil seals;Compact structure;3、 Second generation wheel hub unitThe second generation wheel hub bearings combine the economic a

In addition to tapered roller bearings, deep groove ball bearings, outer spherical bearings, thrust bearings, and so on.Our company has developed and launched a new type of bearing - Trolley Bearings.It a non-standred type.We can customize according to your needs.Welcome your inquiry.

(1) Based on the size and nature of the load     Large load or impact: Select roller bearings (line contact)     Low load or impact: ball bearing selection (point contact)(2) According to the direction of the load     Pure radial load: deep groove ball bearing, cylindrical roller bearing     Pure axial load: selective thrust bearing     Radial axial load: angular contact bearings, tapered roller bearings     Select deep groove ball bearings  when the axial load is not significant (3) Based on th

Recently, a large-scale international bearing exhibition was held in a large exhibition center. The exhibition attracted the participation of bearing manufacturers, suppliers, distributors and professionals from all over the world.Inside the exhibition center, various booths were set up with various types and specifications of bearing products, ranging from common deep groove ball bearings and cylindrical roller bearings to special customized bearings of various brands and models.

Bearings are an important component in contemporary mechanical equipment, whose main function is to support the rotating body of the machinery, reduce the friction coefficient during its movement, and ensure its rotational accuracy. Rolling bearings generally consist of four parts: outer ring, inner ring, rolling element, and retainer. According to the shape of the rolling element, rolling bearings are divided into two categories: ball bearings and roller bearings.

Bearing steel is a steel used to manufacture balls, rollers, and bearing rings. Bearings bear great pressure and friction during operation, so it is required that the bearing steel has high and uniform hardness and wear resistance, as well as high elastic limit.

When designing and manufacturing rolling bearings, the selection of bearing materials is generally based on the following principles.1、 Select according to the working conditions of the bearings①. Working temperatureBearings working at room temperature are made of chromium bearing steel. Chromium bearing steel is also used for working temperatures above 150 ℃ and below 250 ℃, but it needs to undergo special heat treatment (requiring tempering at 200 ℃ or 300 ℃).②.
