The one-way drawn cup needle roller clutch bearing(HF Series) is composed of thin wall punched outer ring and plastic retainer. The punched outer ring is made of alloy steel, and there’s the inradius surface which holds the needles tightly. The needle clutch has very small torque due to its thin radical. Each needle is supported by an independent spring, so higher switching frequency and precision are allowed.
The one-way drawn cup needle roller clutch bearing is greatly increased after special heat treatment. Metal springs are fitted on the plastic retainer which keeps the correct movement of the needles while the needles are used as clamping unit at the same time.
Through fitting the one-way drawn cup needle roller bearing of the same diameter on the two sides of the drawn cup needle clutch bearing, better supporting rigidity and rotation characteristics are achieved.
Commonly used in printing machinery, packaging machinery, textile machinery, food machinery, household appliances, light industrial machinery, and testing equipment.
