Tapered roller Custom bearing manufacturer and supplier by wxingbearing.com? Needle bearing with fine and long roller,so the radial structure is compact,its diameter and load capacity at the same time,with other types of bearing outside diameter to a minimum,especially suitable for the limited size of the radial installation supporting results. Needle roller bearing capacity big,applicable to the limited size of installation supporting structure,the journal as rolling surface hardening on the surface,bearing force fit in a hole,not for axial positioning.Needle roller bearing according to the use of different occasions,the machining accuracy and surface quality should be combined with bearing ring,use.Needle roller bearing is a centripetal needle bearing and thrust bearing parts of the bearing unit.

Joint bearing can bear larger load.According to the different types and structure, can bear radial load, axial load or the joint of the radial, axial load.Because the inside is outside the sphere with composite material, so the bearing can produce self-lubrication at work.Oscillating motion is generally used in low speed, and low speed rotation, can also be tilted movement within a certain Angle, when the supporting shaft and shaft shell hole concentricity is bigger, can still work normally.Self-lubricating bearing joints used in water conservancy, professional machinery and other industries.

At the same time, the oil film also has a certain vibration absorbing ability.Add the lubricating oil, however, one of the biggest disadvantage is need good sealing performance, otherwise it will leak, and some have special requirements equipment lubricating oil leakage is not permitted, so people with other lubrication material to replace the lubricating oil, the invention bearing without oil, make it not only possesses the advantages of containing oil bearing, at the same time to eliminate the environmental pollution caused by leakage.

Entity one-way bearing used GCr15 bearing steel, after heat treatment hardness in HRC61-65, bearing small volume and high bearing capacity, have enough storage space of the grease, but have long come lubrication interval. Powder metallurgy one-way bearing and the real driving force to the shaft in one-way bearings can be completely when the “lock”, to avoid the traditional stamping outer ring one-way bearing “lock” the problem of insufficient performance. Main use: textile machinery;Printing machinery;The automotive industry;Household appliances;Self-checkout counters. HF series: one-way needle bearing is composed of stamping outer ring and plastic cage, cage can bring plastic reed can also on stainless steel reed guided needle, cant on the outer ring raceway and roller as a locking device.HFL (clutch and bearing components) : support bearing installed at both sides of the needle roller clutch and bear radial load, as a support bearing is needle and plastic cage components.Since there is no inner ring, wear of shaft is bigger, so the use of shaft is best for heat treatment.

Slewing ring bearings generally installed with a hole in the gears or gear, grease holes and sealing device, which enable mainframe design compact structure, and guide is simple, easy to maintain.Slewing bearing presence of tooth, tooth and tooth in the four-point contact ball bearing, double row angular contact ball bearing, crossed cylindrical roller bearing, crossed tapered roller bearing and three composite bearings, four row cylindrical roller series, including four-point contact ball bearing has high static load capacity, crossed cylindrical roller with high load capacity, preloaded can make crossed tapered roller bearing bearing has great support stiffness and the rotation accuracy, three rows of cylindrical roller bearing combination height because of the increase to the bearing capacity of bearing, all kinds of power respectively by different race to bear, so under the same stress distribution, the bearing diameter can be significantly reduced, thus make the characteristics of the host more compact is a kind of high bearing capacity of slewing ring bearings.Slewing bearings are widely used in hoisting machinery, mining machinery, construction machinery, port machinery, ship machinery and mechanical precision radar and missile launcher equipment such as large rotary device.At the same time also can according to customer’s specific requirements of the design, development, production various special slewing bearing structure.

Bearing ring (especially the outer ring) under alternating load and impact load, the stress it bears constantly exceeds the fatigue strength limit of the material, leading to the fatigue crack, and the crack eventually expands to a certain extent, leading to the fracture at the maximum stress of the parts.Generally occurs in the bearing area of the outer ring of the bearing, because the outer ring usually fits with the bearing box hole for clearance, and the bearing box body is a variable and elliptical part, which is easy to cause fatigue fracture under alternating load and impact load. Similar to fatigue fracture, when the stress on the bearing is greater than the tensile strength of the material, the inner ring cracks, usually due to improper installation, such as bearing installation tilt, resulting in partial load of the bearing, resulting in partial overload of the bearing caused by fracture;In addition, improper striking during installation caused bearing cracking and falling blocks, which is also classified as overload cracking.Most common interference when installation, and bearing fit size can also lead to large amount of interference of bearing ring crack (mainly has four row cylindrical bearing inner ring interference fit), interference is too big lead to inner ring stress is larger, especially thin cross section thickness (thickness of section < 12 mm) of inner ring, too much interference often leads to inner ring axial crack.

This is definitely a challenge for the machinery industry. However, this challenge was solved in the early 1960s. The British experts in related fields successfully developed oil-free bearings, that is, self-lubricating bearings, which perfectly solved the problem of bearing oil leakage. And self-lubricating bearings were successfully put into high-end machinery manufacturing fields such as aerospace in the late 1960s. Since its development, self-lubricating bearings have become an indispensable existence in many high-end fields.
