Freebear SL4-type with slits

Please try out the freebear “SL4” with slits

Due to scraps or dust, the freebear rotation may not be smooth.Even in this case, by discharging the scraps or dust from the slits, both small balls and a main ball may continue to rotate smoothly.

SL4

We used to use the following method before.

The ball seat was made of cold-rolled steel sheets (SPCC or SPCE), which underwent pressing followed by heat treatment (Carbonitriding, HV500) and unichrome plating on the surface.

At present, the ball seats of C-8Y, C-8L, C-8R and C-5L are made of stainless steel sheets.

Now, heat treatment caused by pressing becomes unnecessary due to hardening, ensuring very high accuracy.

Thus, the durability of our products is greatly improved.

The progress in pressing technology makes slit processing possible.
Those products can also be used in harsh environment such as casting, powder molding and wood panel conveying, etc.

Testing under various assumed conditions

For long-term safe use, we have tested our products under a variety of assumed conditions. To facilitate the use under various environments and ensure high strength and accuracy, we are constantly striving to improve product quality.
