   "Metric rows: Ruland MCL (one-piece) and MSP (two-piece) clamp collars, bore 3 to 50 mm (the catalogue continues to 80 mm). The catalogue (a distributor-hosted copy of Ruland's PDF) prints the same bore, OD, width and screw for both forms; the table gives one row per bore for both part numbers. Inch rows: CL (one-piece) and SP (two-piece), bore 1/8 to 2 in (the catalogue continues to 3 in for CL and 4 in for SP). Screw sizes and seating torques are the catalogue's (alloy-steel / stainless: N·m for metric, lb·in for inch).",
   "Cross-checks: Ruland.com's MCL listing shows MCL-32 (54 mm OD, 15 wide), MCL-34 to 36 (57 / 15) and MCL-38 (60 / 15); the Ruland data sheet for MCL-9-F gives OD 24, width 9, M3 × 10 screw, 2.1 N·m, hex key 2.5 mm, screw location 8.51, clearance Ø26.3 max, bore tolerance +0.050 / +0.012 mm, shaft tolerance +0 / −0.013 mm (its MCLD-10-F page repeats the same figures); distributor titles for MCL-10 (bore 10, OD 24, W 9), MCL-50 (bore 50, OD 78, W 19), MSP-48 (OD 78, W 19) and an OD 34, W 13 one-piece collar agree. The inch CL / SP table has no second source in this fetch.",
   "MCLE: Ruland's 'international series' has inch bores with metric OD and width (for example a 1 in bore, 45 mm OD, 15 mm wide, MCL-16E); the Ruland web page lists sizes but no screw. A distributor title for MCL-16E-SS (bore 1.0000, OD 45 mm) agrees. The number of clamp screws on the two-piece forms is not stated in the pages read.",
   "Files: plain rings at the published bore, OD and width (slit and screw hole are not modelled: the slit width is not published, so a split ring would be invented). The screw and torque are on the table. Ruland offers CAD per part on its site; linked, not copied. Set-screw collars: shaft-collars-clips-and-shafts."

 "sheet_text": "Clamp-style shaft collars, one-piece and two-piece (Ruland MCL / MSP metric 3–50 mm, CL / SP inch 1/8–2 in): bore, OD, width, screw, torque + ring models — dimension sheet\nSource: Xem Studio, https://xemstudio.com/objects/shaft-collars-clamp-ruland/  (sheet CC BY 4.0)\nBasis: Ruland's catalogue tables for one-piece (MCL, CL) and two-piece (MSP, SP) clamp collars, a Ruland data sheet for M3 collars, Ruland.com listing pages (names and sizes) and distributor titles as cross-checks; ring envelopes as files\nCatalog version: 2026-10-20\n\nOverall (mm): length 76.19999999999999, width 76.19999999999999, height 17.475199999999997\n- Metric rows: Ruland MCL (one-piece) and MSP (two-piece) clamp collars, bore 3 to 50 mm (the catalogue continues to 80 mm). The catalogue (a distributor-hosted copy of Ruland's PDF) prints the same bore, OD, width and screw for both forms; the table gives one row per bore for both part numbers. Inch rows: CL (one-piece) and SP (two-piece), bore 1/8 to 2 in (the catalogue continues to 3 in for CL and 4 in for SP). Screw sizes and seating torques are the catalogue's (alloy-steel / stainless: N·m for metric, lb·in for inch).\n- Cross-checks: Ruland.com's MCL listing shows MCL-32 (54 mm OD, 15 wide), MCL-34 to 36 (57 / 15) and MCL-38 (60 / 15); the Ruland data sheet for MCL-9-F gives OD 24, width 9, M3 × 10 screw, 2.1 N·m, hex key 2.5 mm, screw location 8.51, clearance Ø26.3 max, bore tolerance +0.050 / +0.012 mm, shaft tolerance +0 / −0.013 mm (its MCLD-10-F page repeats the same figures); distributor titles for MCL-10 (bore 10, OD 24, W 9), MCL-50 (bore 50, OD 78, W 19), MSP-48 (OD 78, W 19) and an OD 34, W 13 one-piece collar agree. The inch CL / SP table has no second source in this fetch.\n- MCLE: Ruland's 'international series' has inch bores with metric OD and width (for example a 1 in bore, 45 mm OD, 15 mm wide, MCL-16E); the Ruland web page lists sizes but no screw. A distributor title for MCL-16E-SS (bore 1.0000, OD 45 mm) agrees. The number of clamp screws on the two-piece forms is not stated in the pages read.\n- Files: plain rings at the published bore, OD and width (slit and screw hole are not modelled: the slit width is not published, so a split ring would be invented). The screw and torque are on the table. Ruland offers CAD per part on its site; linked, not copied. Set-screw collars: shaft-collars-clips-and-shafts.\n\nseries  part (one-piece / two-piece)  bore  OD  width  clamp screw  seating torque (alloy / stainless)  note\nmetric  MCL-3 / MSP-3  3 mm  16 mm
