Stainless steel bearings are manufactured from corrosion-resistant materials including 304 and 440C stainless steel.

They feature excellent resistance to moisture, rust, acid, alkali and salt spray, making them ideal for harsh and humid environments.

With stable performance, high durability and low friction, these bearings are widely used in food machinery, pharmaceutical equipment, marine applications, packaging lines and automation systems.

Available in ball bearings, roller bearings and bolt-type cam followers, they ensure smooth operation and long service life in clean, corrosive or outdoor working conditions.

XM-RKYR52/0.636160.K is a heavy‑duty V‑groove guide roller bearing of eccentric type. It has a 52mm outer diameter and 1 mm shaft eccentricity, and is built to perform reliably in high‑load linear motion systems.

Engineered for heavy‑duty performance, this unit combines a thick‑walled outer ring with double‑row tapered rollers to achieve superior radial and axial load capacity, strong shock resistance, and long service life in harsh environments. Pre‑lubricated and fitted with dual rubber seals (2RS), it performs reliably in dusty, oily, or high‑vibration working conditions.

It is extensively applied in automated logistics (stackers, AGVs), packaging machinery, CNC machine tools, truss robots, and woodworking/glass processing lines, guaranteeing precise guiding and stable rolling for heavy‑load linear conveying and positioning systems.

RKYR52 differs from RKY52 in that it is equipped with a built‑in eccentric shaft,all other dimensional specifications are the same.

4.091 is a heavy-duty eccentric adjustable combined roller bearing belonging to the Jumbo series. It can withstand both radial and axial loads simultaneously, widely used in heavy-duty linear motion systems.

With an eccentric shaft design, it allows fine adjustment of clearance. Made of high-quality bearing steel or carburized steel, it features high load capacity, reliable sealing and long service life. It is mainly applied to forklift gantry, parking systems, lifting platforms and heavy conveying equipment.

Based on customer requirements, we can provide two product structures: snap ring type and sealing ring type.

However, according to our past experience, the manually injected oil volume is uncontrollable in the sealing ring structure, which may cause the seal to pop out.

The snap ring structure effectively solves this problem.

The 4.458 eccentric adjustable composite roller bearing is a heavy-duty combined bearing that integrates radial and axial load bearings. Its eccentric structure allows for precise adjustment of the installation clearance. It is primarily used in heavy-duty forklifts, stackers, and automated production lines.

It consists of a main roller (radial load, full complement of cylindrical rollers), side rollers (axial load), and an eccentric shaft.

By rotating the internal eccentric shaft (eccentricity approximately 1.5~2.5mm), the axial protrusion of the side rollers (dimension A) can be finely adjusted to compensate for track wear or installation errors.

First, loosen the screws, then rotate the eccentric shaft and measure the gap. Finally, tighten and secure it.

Typical Applications: Heavy-duty forklifts, container stackers, reach stackers; Automated storage and retrieval systems (AS/RS), stacker cranes; Steel metallurgy, conveyor lines, lifting platforms; Tunnel boring machines, construction machinery traveling mechanisms.

The SL1822.. /NCF22.. series bearings are single-row full complement cylindrical roller bearings, belonging to the semi-locating bearing series.

The full complement design, without a cage, makes them suitable for handling large radial and impact loads.

The inner ring typically has two ribs, and the outer ring has one rib. This allows the bearing to axially position the shaft in one direction and withstand axial forces in that direction, while allowing axial displacement in the opposite direction.

Due to their high load and low speed characteristics, the SL1822 series bearings are widely used in:

Construction machinery: such as gearboxes and hoisting machinery.

Heavy industry: metallurgical equipment, mining machinery, and conveying systems.

Transportation: rotating components of ships and vehicles.

4.074/MR148 + AP2  is a combined roller bearing from the standard series of WINKEL Standard Bearing, which allows for precise adjustment of axial by shims. We can supply 0.5mm or 1.0mm shim.This seires bearings don't have grease oil.

The 4.072 combined roller bearing assembled with AP2 flange is a heavy-duty bearing unit designed to withstand both radial and axial loads at the same time.

Its axial clearance can be accurately adjusted by adding different thickness shims between the bearing body and mounting flange, which effectively eliminates axial backlash and optimizes assembly precision.

With fully sealed structure and lifelong pre-lubrication inside, this bearing realizes maintenance-free operation during long-term service.

Featuring stable running performance, high rigidity and strong load capacity, it is widely applied to stackers, warehouse automation equipment, conveyor systems, lifting machinery and other heavy-duty linear motion devices.

If you need to customize non-standard iron plates, we can also provide that.

Our high-precision elliptical guideway conveyor line is a high-end automated conveying solution designed specifically for modern intelligent manufacturing.

It utilizes a closed-loop elliptical track, integrating chain drive and precision linear/circular guideways, achieving industry-leading ±0.05mm repeatability. This ensures stable, slip-free operation and maintains high precision over long periods, making it suitable for high-precision assembly, testing, and machining tasks.

The continuous loop design eliminates idle travel, increasing production efficiency by over 30% compared to traditional linear conveyors. The compact elliptical layout saves 30-50% of floor space, and the central cavity can be used to install auxiliary equipment. The conveyor line employs modular, high-rigidity components, supporting flexible customization of the number of workstations, track shape, and load capacity (single unit load capacity up to tens of kilograms), enabling rapid mold changes and easily adapting to flexible production of multiple varieties and small batches.

Compatible with robots, vision inspection systems, and automated assembly units, this conveyor line offers advantages such as low maintenance costs, long service life, and reliable all-weather operation, making it an ideal core conveying component for automated production lines in the 3C electronics, automotive manufacturing, medical device, lithium battery, and packaging industries.
