PRODUCT SPECIFICATIONS

Ruland MWSP-16-SS is a two-piece double wide shaft collar with a 16mm bore, 34mm OD, and 27.6mm width. The clamp style design does not mar the shaft, is easy to remove, and is indefinitely adjustable. It is commonly used for guiding, spacing, stopping, mounting, and component alignment. Equipment manufacturers benefit from the tightly controlled face to bore perpendicularity (TIR of ≤ .05mm). Perpendicularity is critical for alignment when the shaft collar is used as a load bearing face, mechanical stop, or for mounting components such as gears or bearings. Proprietary processes have been developed by Ruland to maintain superior fit, finish, and holding power. MWSP-16-SS is stamped with the Ruland name and bore size for ease of identification. This double wide shaft collar has 25% higher axial holding power than a round bore of equivalent size. It can also be used as a short rigid coupling for applications where a traditional rigid coupling is too long. Forged screws test beyond DIN 912 12.9 standards to ensure maximum holding power. Halves are mated throughout the manufacturing process for proper fit and alignment. MWSP-16-SS is manufactured from solid bar stock sourced from select North American mills and machined to a fine burr free finish. Ruland uses 303 stainless steel with hardware of like material for consistent corrosion resistance. Stainless steel hardware undergoes a proprietary surface treatment process to prevent galling. MWSP-16-SS is RoHS3 and REACH compliant and manufactured in our Marlborough, MA factory under strict controls using proprietary processes.

Installation Instructions

  1. Use the MWSP-16-SS double wide shaft collar as it is received.
  2. Wipe the bore clean.
  3. Apply a thin coat of light oil to the shaft.
  4. Tighten the screws in two stages, starting with the inside screws. Using a torque wrench with 4 mm bit, tighten the inside screws to 2.7 Nm which is half the recommended seating torque. Repeat for the outside screws, again tightening to half of the recommended seating torque.
  5. On two-piece couplings be sure to maintain the gap between the two halves during installation.
  6. Tighten the screws to the full recommended seating torque of 5.4 Nm following the same pattern, starting with the inside screws first.
