CAT Pin – The Heart of Every Connection
Every pin in a Caterpillar machine performs an extremely important function – it is the heart of the articulated connection. It must withstand enormous cutting and bending forces while being resistant to constant friction. That is why all the pins we offer are made of carefully selected steel, subjected to precise heat treatment (hardening), which ensures maximum surface hardness and a flexible, durable core.
