Cylindrical roller bearings

Our team of skilled engineers marries state-of-the-art technology with the principles of materials science to fashion bearings that epitomize precision and durability. By refining geometries, harnessing advanced lubrication mechanisms, and pioneering sealing solutions, our cylindrical roller bearings emerge as robust entities capable of conquering the harshest operational conditions. These innovative designs don't merely extend the bearing's longevity; they also curtail maintenance demands, resulting in tangible cost savings for our discerning clientele.

Double Row Cam Rollers

The fundamental architecture of double row cam rollers has been meticulously engineered to thrive in demanding operational conditions characterized by high radial loads, misalignments, and abrupt shock loads. Comprising two parallel rows of rolling elements, predominantly cylindrical rollers, these bearings derive their strength from an outer ring with a crowned or cylindrical outer surface.

Four Row Tapered Roller Bearings

Four row tapered roller bearings are critical components in various industries, including heavy machinery, steel manufacturing, and mining, where they are used to support heavy radial and axial loads. These specialized bearings are designed to handle extreme conditions and offer higher load-bearing capacities compared to other bearing types. They are essential for ensuring smooth operation and longevity of equipment in demanding applications.

Deep Groove Ball bearings

Deep-groove ball bearings are common type of rolling bearings. The basic deep-groove ball bearing is composed of an outer ring, an inner ring, a group of steel balls and a group of holding frames. There are two types of deep groove ball bearings，single-row and double-row. The deep-groove ball structure is also divided into two types: sealed and open. The open type refers to the bearing without a seal structure. The sealed deep-groove ball is divided into dust-proof sealed and oil-proof seal. The material of the dust-proof sealing cover is stamped steel plate, which only simply serves to prevent dust from entering the bearing raceway. The oil-proof type is a contact oil seal, which can effectively prevent the grease in the bearing from overflowing.

Screw Compressor Thrust Spherical Roller Bearings

DHK thrust self-aligning roller bearings are available in three different configurations based on different dimensions and cage designs. Small and medium size self-aligning roller bearings can be solid copper cage (suffix MB) or stamped steel cage (suffix J); The standard structure for large self-aligning roller bearings is a solid copper cage (suffix MB).

Four Point Contact Ball Bearings

Four Point Contact Ball Bearings, referred to as 4-point bearings or QJ bearings, are a specialized type of angular contact ball bearings. They are designed to handle combined loads, including radial and axial forces, in a single bearing unit. Unlike traditional ball bearings that predominantly support radial loads, 4-point bearings have a distinctive design that allows them to accommodate both types of loads simultaneously. These bearings are constructed with four points of contact between the balls and the raceways. This unique arrangement consists of two points of contact that primarily support radial loads, and the other two points are dedicated to bearing axial loads. This design enables 4-point bearings to offer increased load capacity and enhanced operational efficiency compared to standard bearings.

Double Row Cylindrical Roller Bearings

Double row cylindrical roller bearings are separable no-locating bearings, which make it mounting or dismounting easy, and both of the bearing rings may be mounted with heavy interference fit to shaft and housing so these bearings only have two basic type. NN type: inner ring with three integral flanges,outer ring without flange. NNU type: outer ting have three integral flanges,inner ring without flange.

Radial Insert Ball Bearings Without Eccentric Locking Collar

DHK insert ball bearings have an extended inner rings, which make it possible of use an eccentric locking collar to locate the bearings on the shaft (series GRAE…NPPB,RAE…NPPB,RALE…NPPB,GE…KPPB3,GE…KRRB, E…KRRB,GE…KLLHB), or to locate it to the shaft with two grub screws (series GAY…NPPB, GLE…KRRB, GYE…KRRB).Series 2…NPPB have all the data same as single row deep groove ball bearing of series 62…exception the spherical out diameters. GSH…RRB series are located on the shaft by the integral adapter sleeves.

Spherical Roller Bearings

Bearings of the design C have symmetric spherical rollers and centre loose rib are fitted with two pieces pressed steel cage as standard. Bearings of the design MB have a centre flange, with asymmetrical rollers and two pieces inner ring riding and machined solid brass cages. This design is produced for the large spherical roller bearings as standard. Such bearings have higher speed capacity.

Spherical Roller Bearings

Bearings with adapter sleeves are composed of two main components: the bearing itself and the adapter sleeve. An adapter sleeve is a cylindrical sleeve that slides onto a shaft and serves as a platform for mounting the bearing. The sleeve can be easily tightened or loosened to achieve the desired shaft position, simplifying the alignment process.
