Ball Bearings FAQS

QHow do the bearings fit into the shaft?

A1, before installing the bearings on the shaft, must first pull off the fixed pin of the fixed bearing jacket, and at the same time smooth and clean the surface of the axle neck, and oil and rust and lubrication at the shaft neck(allowing the bearings to rotate slightly on the shaft). 2, in the bearing seat and bearing surface coated with lubricant, double row conical roller bearings into the bearing seat. The assembled bearings and bearing seats are then placed on the shaft and pushed to the desired position for installation. 3, the bolts of the fixed bearing seat should not be tightened first, so that the bearing jacket can rotate in the bearing seat. The other end of the same shaft bearing and seat is also installed, the shaft is rotated a few times, so that the fixed bearing itself automatically finds the correct position. Then tighten the bearing seat bolt. 4, installed eccentric sleeve. The eccentric sleeve is first placed on the eccentric step of the inner sleeve of the bearing, Tighten with the rotation direction of the hand axis. Then insert or hold the small iron bar against the caisson hole on the eccentric sleeve. Hit the small iron stick with the rotation direction of the hammer axis. Install the eccentric sleeve firmly, and finally lock the inner hexagonal screw on the eccentric sleeve.

QWhat is Self-aligning ball bearing?

AThe self-aligning ball bearing has two structures of a cylindrical hole and a tapered hole, and the material of the cage is steel plate, synthetic resin and the like. The characteristic is that the outer ring raceway has a spherical shape and has self-aligning property, which can compensate for errors caused by different degrees of heart and shaft deflection, but the relative inclination of the inner and outer rings must not exceed 3 degrees.

QWhat is Cylindrical roller bearing characteristics?

AHigh carrying capacity High stiffness; Allow radial displacement Except for bearings with inner and outer ring flanges. Low friction (roller end face / flange contact area) The open flange design, in conjunction with the roller end design and surface finish, promotes the formation of a lubricant film with low friction and high axial basic load ratings. long lasting The roller logarithmic curve profile reduces edge stress at the roller/race contact and sensitivity to misalignment and shaft deflection. Improve operational reliability The surface finish of the roller and raceway contact surfaces facilitates the formation of a hydrodynamic lubricating oil film. Separable and interchangeable The separate components of SKF cylindrical roller bearings are interchangeable. This facilitates installation, disassembly, and maintenance inspection.

QWhat we can provide about the bearing for Oilfield equipment

AWe can offers a full range of large diameter, high quality cylindrical roller bearings in standard and custom designs up to a 60 inches (1,500 mm) outside diameter. These bearings are made of high quality case carburized or through hardened steels. RBC cylindrical roller bearings are available in both bronze pin type retainers and full complement styles. Standard and custom sizes are available in single row, double row, and multi-row versions.
