The four-point contact ball bearing is a separate type of bearing. It can also be said that it is an angular contact ball bearing that can withstand two-way axial load. The inner and outer ring raceways are peach-shaped cross-sections. When there is no load or pure radial load, the steel ball and the ferrule appear as four-point contact, which is the origin of this name.
The rotary table bearing is a kind of precision bearing that can withstand the combined load of axial load, radial load and overturning moment, and combines the functions of support, rotation, transmission and fixing. The rotary table bearing basically adopts the negative clearance belt pre-tightening design to ensure the high rigidity and rotation precision of the bearing. Under normal circumstances, the inner and outer rings of the rotary table bearing have mounting holes, lubricating oil holes and sealing structure, which are suitable for precise working conditions. The different installation and use requirements of various types of equipment; rotary table bearings have the characteristics of compact structure, high rotation precision, easy installation and maintenance, etc. The rotary table bearings mainly include YRT rotary table bearings, ZKLDF rotary table bearings and cross roller bearings. These three series of bearings have the same mounting dimensions, different internal structures and similar performance.

Mud pump bearings
Four-row cylindrical roller bearings: The rolling element and the ferrule rib have small friction and are suitable for high-speed rotation. According to the ferrule with or without ribs, it can be divided into single row bearings such as NU, NJ, NUP, N, NF, and double row bearings such as NNU and NN. The bearing is a structure in which the inner ring and the outer ring are separable. Cylindrical roller bearings with no ribs on the inner or outer ring, the inner and outer rings can move relative to the axial direction, so they can be used as free end bearings. A cylindrical roller bearing with a single rib on one side of the inner and outer rings and a single rib on the other side can withstand a certain degree of axial load in one direction. Steel stamping cages or copper alloy cages are generally used. However, some use polyamide shaped cages.
Double row inch taper roller bearings
The outer ring (or inner ring) of the Double row taper roller bearings is a unitary body. The inner rings of the two inner rings (or outer rings) are similar, and the spacers are arranged in the middle. The clearance is adjusted by the thickness of the spacers. The thickness of the spacers can also be used to adjust the pre-interference of the double-row tapered roller bearings.
Four row inch taper roller bearings
Four row taper roller bearings have been successfully used in bearing configurations for rolling mills around the world at low to medium speeds. Due to its design, such bearings are capable of withstanding axial loads occurring in such applications outside of radial loads, and generally do not require additional thrust bearings in the bearing arrangement. This means that the roll journals can be relatively short and the bearing housings on both sides of the roll can be of the same design. Due to the design of the four-row tapered roller bearing, this bearing must be mounted as a complete bearing on the roll chock. In order to be able to change rolls quickly, such bearings must be loosely fitted over the roll journal. The disadvantage of the loose fit is that the inner ring creeps on its base under the main load conditions, which usually causes wear of the base with a lower hardness than the bearing ring. In order to reduce the influence of loose fit to a certain extent, that is, to reduce wear, the bearing has a spiral groove in the inner ring hole, and/or an oil groove on the side of the inner ring. These oil grooves feed the lubricant to the contact surfaces of the inner ring and the base. In addition, the grease filled tank absorbs wear particles
