The "TLH Roller Chain" is composed of a three-layer special coating. The mechanism prevents moisture and oxygen with each layer, suppressing corrosion. An interdiffusion area is created at the boundary between the second and third layers, which strongly adheres to suppress the occurrence of red rust for an extended period. If the top coat of the third layer is scratched, molecules from the coating gather around the scratch and cover it, providing a repair effect. 【Features】 ■ High corrosion resistance ■ Composed of a three-layer special coating ■ Each layer prevents moisture and oxygen, suppressing corrosion ■ Suppresses the occurrence of red rust for an extended period ■ Molecules from the coating gather around scratches and cover them, providing a repair effect *For more details, please refer to the related links or feel free to contact us.

"MIM" stands for Metal Injection Molding, which refers to the process of metal powder injection molding. It involves mixing metal powders of less than 10 microns with a binder made of resin and wax, forming the material, and then debinding and sintering it to manufacture metal products. This technology is highly productive and suitable for mass production of complex-shaped parts, offering potential cost advantages. 【Features】 ■ A wide variety of metals, including difficult-to-machine materials, can be used ■ High precision processing with a tolerance of ±0.5% on dimensional values ■ Capable of near-net-shape three-dimensional forms ■ Higher strength than conventional powder metallurgy can be achieved ■ Cost advantages are expected *For more details, please refer to the related links or feel free to contact us.

This product is a coupling ring that consists of two sprockets and one roller chain, assembled with a two-row roller chain that engages with the teeth of the sprockets all around, allowing for connection and disconnection of both shafts with a single pin, resulting in a structure that is very simple and rich in flexibility. It is designed to effectively utilize the play created by the engagement of the chain and sprockets to protect the machinery. Additionally, to achieve excellent durability, the tips of the sprockets are surface-hardened, and the roller chain used for this purpose is specially tempered for coupling use, allowing it to withstand long hours of operation. Furthermore, this product, which has numerous features such as being compact, powerful, and easy to handle, is used in a wide range of applications. [Features] - Easy alignment - Excellent durability - Compact and powerful - Easy to handle - Safe and smart *For more details, please refer to the catalog or feel free to contact us.

The "Slew Chain J-SER Type" is an oil-free roller chain that is ideal for environments that require cleanliness and dislike dirt, as well as for areas where lubrication is difficult. It uses a sintered alloy that has been impregnated with a special lubricant in the bushings, allowing for long hours of operation without the need for oil due to its self-lubricating properties. The standard specifications include plates treated with phosphate coating and bins that are nickel-plated. Additionally, for strength considerations, the inner plates are thicker, but it is compatible with general-purpose roller chains and can use OCM standard sprockets as is. 【Features】 ■ Self-lubricating, allowing for long hours of operation without oil ■ Compatible with general-purpose roller chains ■ Can use OCM standard sprockets as is *For more details, please refer to the catalog or feel free to contact us.
