(see dimensions) T1 is the same on both rails. Ordering example: Size 20 Desired length: 620 to 625 mm nB = 620/T = 620/62.5 = 9.92 rounded (whole numbers) = 10 bores nT = nB - 1 = 9 Rail length (L) to be ordered: L = 10 · 62.5 - 4 = 621 mm or L = 9 · 62.5 + 2 · 29.25 = 621 mm Guide rail: R192311931, 621, 29.25 / 9 x 62.5 / 29.25 Material number, length (mm)1 / nT x T / T1 (mm) Legende Symbol Description Unit L Rail length mm T Hole spacing mm T1S Preferred dimension mm nB Number of holes nT Number of hole spaces Downloads Profiled rail systems Manual | R320103885_EN | 2016-09-01 | English | PDF | 11.5MB Product Groups: Linear guides Cam Roller Guides Catalog | R999000486 | 2018-12-01 | English | PDF | 3.3MB Product Groups: Cam Roller Guides
