Essential phrases to know HAMMER CASTER.
Hammer Caster has started their own caster production when casters are not even commonly
spread in Japan. Kept in a different form, the founder's sincere attitude towards the productmaking has been steadily taken over to next generations for over a century.

STS (Stainless steel)

Synthetic resin (Plastic)

Steel is a commonly used material forindustrial casters. Surface treatment canalso be applied to a wide range ofapplications, including plating that meetse nv i r o n m e n t a l r e g u l a ti o n s a n d h e a ttreatment to improve durability.

Stainless steel is excellent in water
resistance and corrosion resistance, and isof ten used in kitchen equipment that
requires resistance against rust andchemicals that contains solvents.

The plastic body softens the cold impressionof metal. Because of its high design and low
nois e , i t is sui t able f or indo or u s e in
hospitals and offices.

●2 Swivel (at front) x 2 Fixed (at handle side)This combination is commonly used in factories and distribution
warehouses and is ideal for carrying light packages. By placing a fixed
type on the handle side, the driving direction is stabilized, so that thepush cart does not shake from side to side. It is not suitable fortransporting heavy objects because a large force is required forturning.

It is a combination used when carrying a large load or heavy load. By
arranging the swivel type on the handle side, the lever principle isapplied and the direction can be easily changed. When carrying an
empty load or a light object, the straight movement operation is lessthan that of the "2 fixed (at handle side)".

It is a combination used in shopping carts and flat carts. By making all
four wheels swivel, it has the advantage of being able to move in thedesired direc tion from a spot, and it is convenient for lateral
movements. Easy to operate on a flat floor but goes less straight on aroad surface with a slight slope.

In case of using wheels or casters are in a cold environment, it is necessary to change the specification
to cold-resistant. In addition, it is necessary to use it in a manner suitable for low-temperatureenvironments. Please consult our sales office for details.

●Parts that need to
be changed in caseof cold weather

■For casters①Grease tobearing bore
②Grease toswivel sectioon①■For wheels②①①Grease tobearing bore

Be careful of condensation.
If the caster is used again in a cold environment
without being sufficiently dried , the water dropletsfrom condensation may freeze, causing improperswivel or wheel revolving.

Make sure to dry throughly for a while
after using in the cold environment.

Conductive Casters / Antistatic Casters
Eliminating static electricity keeps dust out of casters and prevents problems
caused by static electricity.
It plays the role of earth to let theelectricity from equipment andmachinery escape to the floor.
