Define the fitting dimension
B21 is the brass ferrule with a rubber sole. Its catalogue size reference is 10–30 mm. Identify the required dimension and which surface it describes in your drawing or enquiry; do not assume one part covers the complete reference range.
Describe the body and contact surface
The catalogue identifies a brass body and rubber sole. Include any requirements for the brass, contact material, visible finish and intended use separately. Final construction and fitting details belong in the approved specification, rather than being inferred from the product photograph.
Check the assembled sample
Review how the proposed sample fits the intended shaft, together with the agreed dimensions and appearance. Include B21, quantities, destination and pack requirements in your RFQ. Any performance or documentation needs should be stated before quotation; no load rating or slip-resistance result is established by this catalogue entry.
The approved sample and written quotation define the final specification and order terms. See our sample and ordering guide before confirming an order.
