Material and Function of Buffer Rubber Sleeve for Spring Balancer?

The buffer rubber sleeve fitted on the spring balancer is extremely critical. Though it is a small component, it delivers great performance and is an indispensable part. In the following content, manufacturer Hebei Shengyu elaborates on the function and material of the buffer rubber sleeve for spring balancers.

1. The buffer rubber sleeve of the spring balancer is mounted at the lower end of the balancer. It provides buffering and anti-collision effect when the tool retracts rapidly. It prevents direct collision of metal components, reduces impact noise, eases the instantaneous impact force on the hook and steel wire rope, lessens wear of parts, avoids structural damage, and effectively extends the service life of the spring balancer, steel wire rope and hook.

2. There are two main types of materials for buffer rubber sleeves of spring balancers. High-quality ones adopt polyurethane (PU), featuring wear resistance, impact resistance, resistance to friction from steel wire ropes, excellent cushioning performance and long service life. Economy versions are mostly made of natural rubber, which is soft and low-cost yet poor in wear resistance and prone to aging when exposed to oil. EPDM is adopted for a few outdoor applications with great weather resistance but inferior wear performance to PU. Polyurethane is preferred for lifting working conditions.
