  4. 1T Series - Pure Titanium Bearings

Features

Corrosion Resistance

Usable in severer corrosive environment than austenitic stainless bearing made of AISI304, by using high corrosion resistant pure titanium class 2 for outer and inner rings.

Safeness

Human-friendly without allergen reactions, as usable as in artificial joints.

Low Temperature Characteristics

Usable in low temperature environment by good low-temperature toughness.

Materials

SMT 1T Series - Pure Titanium Bearings

Applications

Food Machinery, Seawater-related Equipment, Plating Machine, Electronic Device, Equipment used in Low Temperature, Etching Equipment, Developing Machine, Medical Equipment, etc.
