Bearing for Forklift Truck

Mast Roller Bearing

Chain Sheave Bearing

Side Roller Bearing

Bearings for forklifts are divided into mast roller bearings, chain sheave bearings, and side roller bearings, and YHS BEARING manufactures all three types of bearings.

These bearings are commonly used in harsh environments that are repeatedly exposed to eccentric loads, high radial loads, and extreme impact loads.

The products YHS BEARING are made of sealed forged materials and go through a hardening heat treatment process exclusive for bearings to maintain the highest quality in extreme environments.

Beside the existing manufacture standards size, the company is also working on non-standard manufacture size based on orders.

This bearing is installed inside the mast of forklift, and guides the linear movement of the mast.

The bearing plays the role of guiding and sustaining the stable transportation of fork carriage in the mast.

Specially designed with a thick outer ring, the bearing has high durability and excellent shock resistance.

This bearing is installed on the chain shaft for the vertical movement of the fork.

The bearing features wings on both ends of the outer ring to guide the transfer of the lift carriage and the chain belt movement of the fork.

Snap rings with special design are used. Thanks to a number of surface treatments, the bearing has outstanding corrosion resistance even in outdoor areas.

This bearing supports the lateral load generated during the vertical movement of fork carriage and guides the transfer of carriage within the mast.

The bearing is a single/multi-row needle roller bearing designed to withstand high radial loads with a limited diameter, providing excellent durability while receiving constant impacts in tight spaces.

Bearing for Telescopic Crane Car

18

Bearings for telescopic crane car are mainly divided into wire type and chain type, and YHS BEARING manufactures both.

These bearings are commonly resistant to eccentric load, high load, and high radial load, and have excellent corrosion resistance even in outdoor areas.

In addition, the bearings use sealed forged materials and go through a hardening heat treatment process exclusive for bearings as well as a number of surface treatments to have outstanding durability and maintain the highest quality in any environment.


Wire Guide Bearing

Leaf Chain Sheave Bearing

This bearing guides the transfer movement of wire inside the boom of telescopic crane cars.

Snap rings with special design are used. Top quality is maintained through a number of material treatments.

The bearing is manufactured as a ball type.

This bearing guides the transfer movement of wire inside the boom of telescopic crane cars. It is used as a BL/AL chain guide for leaf chain.

The bearing is manufactured as a roller ball type or ball type. Based on the load, the bearing has a single/double/multi-row design.

Bearings for Industrial Line Systems

Among the industrial lines/systems, large conveyor chains used in steel mills etc frequently transfer heavy objects.

YHS BEARING manufactures roller bearing products specialized for such heavy-duty transfer lines.

Compared to ordinary bearings, these special bearings have higher impact resistance, rigidity, and durability.


23


In large conveyor chains, this is a type where the guide bearing is connected to the inside of the inner link. Based on the shape of bearing, the guide type bearing is divided into a guide roller bearing and an F-roller bearing.

Specialized for heavy-duty transfer lines, the guide type has higher impact resistance, rigidity, and durability than ordinary roller-type conveyors. Repair and installation are also convenient by changing the bearing.

Guide type : Guide Roller Bearing / F-Roller Bearing

Side type : Side Roller Bearing / F-Roller Bearing

In large conveyor chains, this is a type where the bearing is connected to the both sides of the outer link. Based on the shape of bearing, the side type bearing is divided into a side roller bearing and an F-roller bearing.

Specialized for heavy-duty transfer lines, the side type has higher impact resistance, rigidity, and durability than ordinary roller-type conveyors. Repair and installation are also convenient by changing the bearing. Using the side type, rail transfer becomes more stable than the guide type.
