Rubber tire

Clearance seal type MFC type

There is no seal lifetime because this is non-contact seal type.
Furthermore, it is low heat generation and low dust emission.

For water and hot water (Applicable industry: General machinery) LC type

There is no seal force trouble caused by accumulated contamination in the fluid and water scale on spring part because spring for seal force is not in the fluid.

For hot water and heat transfer oil (Applicable industry: General machinery) LCH type

Applicable for maximum temperature 200 ℃ because packing and grease have heat tolerance.
Furthermore, no regular oil supply is needed.

Applicable industry: Rubber and tire NB type

This rotary joint is superior to environmental resistance because material of main parts is Cu alloy and Stainless steel.
Maintenance free and no oil supply is needed.

Rocky Insulator

We provide our customers with products made from phenolic resin materials and glass fibers, which are formed by heat and direct pressure integral molding using a molding machine, and which have been processed into various shapes. Thermal insulation, as well as strength, is a heat-resistant and heat-insulated plate that has been highly evaluated by customers.

FRICTTLE

A conventional lubricant forms an oil film to lubricate the sur face of metal.
FRICTTLE is a completely new lubricant because metal surface modification is also applied to lubricate the surface. FRICTTLE reduces friction overwhelmingly and remarkably prolongs the service life of metal components o wing to its incomparable lubricity.
Also, FRICTTLE can decrease noise by lowering friction-induced vibration.

Hardlock Nut (HLN)

Utilizing the wedge principle used in ancient Japanese architecture, the HLN is the ultimate self-locking nut which perfectly succeeds to integrate the nuts with the bolt.

Hardlock Bearing Nut (HLB)

The HARDLOCK Bearing Nut was developed with the same wedge design as HARDLOCK Nut and maintains an extremely effective self-locking effect. The HARDLOCK Bearing Nut's high self-locking effect allows it to maintain a complete tightened state even during high-speed rotation, vibration, forward and reverse rotation and impact. We promise a significant cost down since it is maintenance-free.

Hardlock Set Screw (HLS)

The HARDLOCK Set Screw is a revolutionary self-locking set screw (Hexagon socket head set screw) which applies the "wedge principle" and delivers superior self-locking effect like the other HARDLOCK products without any change in the current conditions of the application.
