Frequently Asked Questions

What is the BOSTON GEAR Oil Resistant Spider Insert used for?

The BOSTON GEAR Oil Resistant Spider Insert is a high-torque straight jaw spider designed for FC30 coupling size. It transmits power between shafts in industrial machinery, such as pumps and gearboxes, while absorbing shock and compensating for minor misalignment. Its oil-resistant rubber construction suits environments where lubricants or oils are present.

What are the specifications of the BOSTON GEAR XFCR30 spider insert?

The BOSTON GEAR XFCR30 spider insert has a 3 in outside diameter, a power rating of 1.30 hp, and is made of oil-resistant rubber. It fits FC30 coupling size and uses inch dimensions. The manufacturer part number is XFCR30, and it is designed for high-torque straight jaw couplings.

Where to buy BOSTON GEAR spider inserts worldwide?
