According to the different requirements of bearings and bearing seats, the classification of bearing seats is not exactly the same, and it is necessary to carefully check the selection according to the design when using.1 Classification according to the shape of the bearing seat:1.1 Outer spherical bearing with seat, also known as bearing unit (SKF). When there is no bearing, it is called the outer spherical bearing seat. 1.1.1.1 The outer spherical bearing seat is divided into 200 series according to the bearing series. The 500 series. The 300 Series. The 600 Series.

The insulated bearing adopts a special spraying process to spray high-quality coating on the outer surface of the bearing. The coating has strong adhesion to the substrate and good insulation performance, which can avoid the electric corrosion of the bearing by the induced current, prevent the damage of the current to the grease, the rolling element and the raceway, and improve the service life of the bearing. The process is constantly improving. In insulated bearings, the outer ring or inner ring surface has a layer of 100μm thick coating, which can withstand voltages up to 1000V DC.

Excavator bearing installation and removal methods, should be according to the excavator bearing structure, size and excavator bearing parts with the nature.Installation, disassembly pressure should be directly added to the end face of tight fit excavator bearing stalls circle, not by the excavator bearing rolling elements to transmit pressure, because this will be caused by the excavator bearing work surface indentation, impact excavator bearing normal workeven make excavator bearing damage.

Outer spherical bearing with seat is a high-precision component product composed of greased sealed deep groove ball bearings and bearing seats of various shapes.

The range of four-row tapered roller bearings is wide, including not only the traditional design with an intermediate ring between the outer ring and/or the inner ring, but also the modification of the four-row tapered roller bearings with an integrated middle ring and the bearing ring.New domestic modelsOld domestic modelInner diameter (mm)Outer diameter (mm)Width(mm)Cr(kN)Cor(kN)Grease lubrication speed (r/min)Oil lubrication speed (r/min)Weight (kg)302027202E15351114.913.412000160000.053302037203E17401220.821.89000120000.079302047204E20471428.230.58000100000.126302057205E25521532.2377000900

Double-row tapered roller bearings are usually used in applications that require large loads and high-speed rotation, such as wind turbines, metallurgical equipment, rolling mills and heavy machinery, etc.

Rolling bearing with seat is a common and widely used in various mechanical equipment bearings, which support and transmit rotating motion through rolling elements, with high load capacity and stability. Below I will describe in detail the structure, working principle and application areas of rolling bearings with seats, hoping to help you better understand this knowledge.A rolling bearing with seat is usually composed of several basic parts, such as an inner ring, an outer ring, a rolling element (such as a steel ball, roller, etc.) and a cage.

High load carrying capacity    The cage bars are displaced relative to the roller pitch diameter to enable the rollers to be placed closer to each other, creating room for additional rollers  High stiffness    The increased number of rollers increases radial stiffness.    High speed capabilityThe cage designs are suitable for high speeds, rapid accelerations and peak loads.  Long service life  The black oxide coating of rings and rollers (designation suffix L4B) contributes to extended service life by improving:     

Product Description:Can manufacture mechanical shell, frame and other structural components.

Spruce develops and supplies a wide range of axles, drive units and traction motor bearings for railway rolling stock. These bearings feature high performance, high reliability and long-term maintenance-free service to support railway companies in providing fast, safe and reliable transport.Axle bearings: tapered roller bearings, tapered roller bearing cartridge, cylindrical roller bearings, spherical roller bearings.Railway axle bearings are subjected to heavy impacts and loads.

Deep groove ball bearings are the most widely used bearing type and are particularly versatile. They have low friction and are optimized for low noise and low vibration which enables high rotational speeds. They accommodate radial and axial loads in both directions, are easy to mount, and require less maintenance than other bearing types  1 Type: Single row deep groove ball bearings,Stainless steel deep groove ball bearings,Single row deep groove ball bearings with filling slots,Double row deep groove ball bearings 2.

Bearing capacity: NTN angular contact bearings have high bearing capacity and can withstand large radial and axial loads. In the process of use, the axial load of the bearing will cause the contact pressure between the inner and outer rings to increase, so it is necessary to choose the appropriate contact Angle to improve the bearing capacity.Rotation accuracy: NTN angular contact bearings have high rotation accuracy, which can ensure that the mechanical equipment has stable rotation performance during operation.

The structural design of the stud CAM follower needle bearing consists of an end plate integrated into the inner ring (stud) and another inner shoulder ring pressed against the stud. In this design, both ends of the stud have lubrication holes to ensure that the bearing can be fully lubricated during operation. The inner ring is hardened by induction, which can improve the hardness and wear resistance of the inner ring, thus extending the service life of the bearing.

Product Description:Manufacture a variety of mechanical structural components, such as machine workbench, robot arms, etc.

A double-row tapered roller bearing is a common bearing type that consists of two tapered rollers mounted on an inner ring and an outer ring. It can withstand large radial and axial loads and is able to maintain high accuracy and stiffness while rotating at high speeds.Double row tapered roller bearings are designed so that the inner and outer rings can be adjusted separately to achieve axial and radial preloading.
