What is freebear
① Conveying by means of balls
Roller conveyors can only move workpieces
linearly, while freebears that use balls can move
360°.
② Low starting frictional resistance
By using freebears, the friction on the load
changes from “sliding friction” to “rolling friction”,
which can easily move the load.(Starting frictional resistance refers to the initial resistance when moving a heavy object from rest.)
Freebear structure
① Upward and downward freebears
Upward type
Put the small balls in the ball seat,
and then put a main ball on them to rotate.
※Please consult us for your use in the oblique and horizontal directions.
Downward type
The downward ball seat is mounted inside,
in which the small balls circulate.
② Press-molded products, Cutting-machined products
Press-molded products
The ball seat is press-molded.⇒ made from sheet metals.
What is press molding
A processing method for forming sheet metals or the like by applying a pressure on the mold.
Cutting-machined products
The ball seat is cutting-machined.⇒ made by cutting round bars.
What is cutting machining
A processing method using a tool to cut the material into a certain shape.
From the above, the wall thickness of R face of press-molded product is relatively
thin, while that of cutting-machined product is relatively thick.
※The weight of a single load for press-molded products shall not exceed 1000 kg.
