LINEAR MOTION SYSTEMS Part Number System SteadyRail™ Linear Motion Systems (Formerly: LM Systems) 04 J CS Txx B Notes: Standard Travel Lengths: 06, 12, 18, 24, 30, 36, 42, 48 Type 1 and 2 use System Length (LXX), Type 3 and 4 use Travel Length (TXX)

STAGE 1 TYPE A & B - End Supported System Type A / Single Pillow Blocks L1 Unit: inch * Based on a travel of 2 million inches. System Type Standard System Lengths (L) Stage 1 - B Travel length is calculated by subtracting the pillow block length (L1) and both the end support block length (L2) from the total system length (L).

LINEAR MOTION SYSTEMS STAGE 1 TYPE C - End Supported System Type C / Single Pillow Blocks Travel length is calculated by subtracting the carriage length (L1) and both the end support block length (L2) from the total system length (L). Unit: inch

LINEAR MOTION SYSTEMS STAGE 1 TYPE D - End Supported System Type D / Double Wide Pillow Blocks Travel length is calculated by subtracting the carriage length (L1) and both the end support block length (L2) from the total system length (L). Unit: inch

LINEAR MOTION SYSTEMS STAGE 2 TYPE A & B - Continuously Supported System Type A / Single Pillow Blocks Unit: inch Travel length is calculated by sub-tracting the pillow block length (L1) from the total system length (L).

STAGE 2 TYPE C - Continuously Supported System Type C / Single Pillow Blocks Travel length is calculated by subtracting the carriage length (L1) from the total system length (L). Unit: inch Part No. Shaft Dia. Max. Load (lbs.) L1 D Thru Hole / Bolt Size

STAGE 2 TYPE D - Continuously Supported System Type D / Double Wide Pillow Blocks Travel length is calculated by subtracting the carriage length (L1) from the total system length (L). Unit: inch Part No. Shaft Dia. Max. Load * (lbs.) L1 B1 B2 B3 D Thru Hole / Bolt Size

LINEAR MOTION SYSTEMS STAGE 3 TYPE A - End Supported System Type A / Single Pillow Blocks Unit: inch * Based on a travel of 2 million inches. Unit: inch Travel Overall System Length (L)

STAGE 3 TYPE B - End Supported System with Ball Screw Type B / Single Pillow Blocks Unit: inch * Based on a travel of 2 million inches. Unit: inch Travel Overall System Length (L) Various ball screw & lead screw options available. See page 4 for standard options Please specify screw lead when ordering or call BWC for available options.

LINEAR MOTION SYSTEMS STAGE 4 TYPE A - Continuously Supported System Type A / Single Pillow Blocks Unit: inch * Based on a travel of 2 million inches. ** For 12", 24", and 36" travel lengths subtract 1" of "Y" dimension. Unit: inch Travel Overall System Length (L)

LINEAR MOTION SYSTEMS STAGE 4 TYPE B - Continuously Supported System with Ball ScrewType B / Single Pillow Blocks Unit: inch * Based on a travel of 2 million inches. ** For 12", 24", and 36" travel lengths subtract 1" of "Y" dimension. Unit: inch Travel Overall System Length (L) Various ball screw & lead screw options available. See page 4 for standard options Please specify screw lead when ordering or call BWC for available options.

TECHNICAL GUIDE BASIC DYNAMIC LOAD (C ) This term is arrived at based upon evaluation of a number of identical linear systems individually run in the same conditions. 90% of them can run with the load (with a constant value in the constant direction) for a distance of 2,000,000 inches without damage caused by rolling fatigue. This is the basis of this rating. BASIC STATIC LOAD RATING (CO) This term defines a static load such that at the contracting position where the maximum stress is exercised, the sum of the permanent deformation of the rolling elements and that of the rolling plane is...

TECHNICAL GUIDE SHAFT DEFLECTION The function and the service life of a system can be greatly reduced and even cause premature failures if shaft deflection is not observed. We have provided an equation to help calculate the maximum shaft deflection for your selected condition. D = Deflection (in) L = Distance between shaft and support (in) E = Modulus of elasicity (lbf / in2 ) I = Shafts moment of inertia (in4 ) S = Shaft unit weight (lbf / in) F = Load (including carraige weight) (lbf) A = Distance between carriage bearings (in) B = (L - A) / 2 (in) LOAD CONSIDERATIONS The loads acting...

Vertical Load At the time of movement with uniform velocity or at the time of stop. At the time of acceleration, the load varies because of inertia. Side Mounted Load Horizontal Load At the time of movement with uniform velocity or at the time of stop. At the time of movement with uniform velocity or at the time of stop. Equation Terms: d0 = Distance between centerlines of pillowblocks (in) d1 = Distance between centerlines of shafts (in) d2 = Distance from centerline of carriage to load action point (in) F1X ~ F4X = d3 = Distance from centerline of carriage to load action point (in) FNX =...
