BXU Series Crossed Cylindrical Roller Bearing Parameters

BXU Series Crossed Cylindrical Roller Bearing Introduction

BXU series crossed cylindrical roller bearing is a bearing with a special structure, in which the cylindrical rollers are arranged vertically on the 90° V-shaped groove rolling surface through spacers. This design enables the bearing to withstand loads in multiple directions such as radial loads, axial loads and moment loads.

This series of bearings has the characteristics of miniaturization, especially in extremely thin form, close to the limit of small size. At the same time, it has high rigidity and high precision, and can reach P5, P4, P2 grades. This makes BXU series bearings especially suitable for joints and rotating parts of industrial robots, rotary tables of machining centers, precision rotary tables, medical equipment, calculators, military industry, IC manufacturing equipment and other equipment.
BXU series crossed cylindrical roller bearings consist of thick-walled outer and inner rings, cylindrical rollers, spacers and fixed mounting holes. In order to provide better sealing performance, contact seals or labyrinth seals are usually used. The inner and outer rings are connected to the surrounding parts by bolts to ensure the installation and fixation of the bearing.
Features of BXU series crossed cylindrical roller bearings
1: Bear multi-directional loads: BXU series bearings use cylindrical rollers arranged vertically on the V-shaped groove rolling surface through spacers, so that they can bear loads in multiple directions such as radial loads, axial loads and moment loads.
2: Size miniaturization: The inner and outer rings of this series of bearings are small in size, especially the extremely thin form, which is close to the limit of small size, but still has high rigidity. The precision can reach P5, P4, P2 level, which is suitable for applications with higher precision requirements.
3: Wide range of application fields: BXU series bearings are suitable for joints and rotating parts of industrial robots, rotating tables of machining centers, precision rotating tables, medical equipment, calculators, military industry, IC manufacturing equipment and other equipment. Its high stiffness and precision make it excellent in applications requiring precise positioning and high-speed rotation.

4: Structural features: BXU series bearings have thick-walled outer and inner rings, cylindrical rollers, spacers and fixed mounting holes. Usually contact seals or labyrinth seals are used to provide better sealing performance. The inner and outer rings are connected to the surrounding parts by bolts to ensure the installation and fixation of the bearing.

Installation method

Preparation of components before installation

Check that the seat of the bearing is intact.

Clean the base of the bearing and related parts to ensure that the surface is flat and free of burrs, burrs and other protrusions, so as to avoid affecting the installation and normal operation of the bearing.
The specific steps of installation

Place the bearing on the seat of the bearing.

Pad a flat, non-hard material on the bearing surface to prevent damage to the bearing during knocking.

Gently tap the bearing with a hammer to slowly install it into the seat until the bearing bottoms out or makes a dull sound.

After the installation is complete

Inspect the bearing visually to make sure there is no visible damage or deformation.

Turn the bearing and watch the speed to make sure there is no unusual noise or drag.
