Ruland MBS33-13-11-A, 13mm x 11mm Bellows Coupling, Aluminum, Set Screw Style, 33.3mm OD, 42.9mm Length

PRODUCT SPECIFICATIONS

Ruland MBS33-13-11-A is a bellows coupling with 13mm x 11mm bores, 33.3mm OD, and 42.9mm length. It is zero-backlash and has a balanced design for reduced vibration at high speeds. MBS33-13-11-A is comprised of two anodized aluminum hubs and a stainless steel bellows. The bellows are able to flex while remaining rigid under torsional loads allowing for all types of misalignment to be accommodated. This bellows coupling is lightweight and has low inertia making it suitable for applications with speeds up to 10,000 RPM. Hardware is metric and tests beyond DIN 912 12.9 standards for maximum torque capabilities. Ruland manufactures MBS33-13-11-A to be torsionally rigid and an excellent fit for precise positioning stepper servo applications as well as encoders. It is machined from solid bar stock that is sourced exclusively from North American mills and RoHS2 and REACH compliant. MBS33-13-11-A is carefully manufactured in our Marlborough, MA factory under strict controls using proprietary processes.

Product Notes

Note 1

Stainless steel hubs are available upon request.

Note 2

Torque ratings are at maximum misalignment.

Note 3

Performance ratings are for guidance only. The user must determine suitability for a particular application.

Note 4

Torque ratings for the couplings are based on the physical limitations/failure point of the metal bellows. Under normal/typical conditions the hubs are capable of holding up to the rated torque of the metal bellows. In some cases, especially when the smallest standard bores are used or where shafts are undersized, slippage on the shaft is possible below the rated torque of the metal bellows. Keyways are available to provide additional torque capacity in the shaft/hub connection when required. Please consult technical support for more assistance.
