The Cam Followers is a highly rigid bearing, which consist of needle rollers between a shaft and a thick outer ring.

The thick outer ring is capable of bearing both large radial load and impact load while keeping direct contact with the guiding surface.

MINIATURE TYPE

The outside diameter of the outer ring is small compared to the stud diameter. Therefore, the bearings are used in compact product design.

EASY MOUNTING TYPE

The bearing has a stepped tapered portion on the stud, which makes its installation easy by just fixing a set screw to the stepped portion.

STANDARD TYPE

ECCENTRIC TYPE

The bearing shaft's mounting part and the bearing part are eccentric. It is possible to adjust the distance between the bearing and the track by turning the shaft.

TAP HOLE TYPE

The bearing has tap hole for piping, which can be used in a concentrated lubrication system.

FULL COMPLEMENT DOUBLE ROW TYPE

The bearing has a full complement of cylindrical rollers in double row. It is capable of carrying large radial load.

S Lube Needle Bearings

S Lube Needle Bearings are bearings with solid-type lubricant moulded into the bearings.

S Lube is lubricant made of lubrication oil and ultra-high molecular weight polyethylene that are solidified by heat treatment. It contains a large amount of lubrication oil. This type of solid lubricant allows the bearing to have a long service life by providing it with consistent lubrication oil in a proper amount.

Characteristics

* Corrosion-resistant stainless materials

  Stainless needle bearings are suitable for use in industries where corrosion resistance is needed such as medical device, food machinery, printing machinery and packaging machinery. This product is also available in standard steel type.

* Minimizes condemnation of the surrounding environment

  The optimized solid lubricant structure retains oil in the bearing thus minimize the oil leakage.

* Strong protection against ingress of water and dusts

  Structurally it prevents against ingress of contaminants. Even if it touches water the lubricant will not be washed out. The stainless type will further resist corrosion and  damages against water.

* Maintenance free

  Since the bearing supports consistent lubricant oil supply, lubrication maintenance is reduced over long-term use.
