ProductMBG · MBR — Metric thread single nut (MBG = ground; MBR = rolled).
Part number constructionExampleMBG | 06 | 01 | D | X | - | 60 | R | 90 | C3 | Z | - | 001
- ① Series: MBG = Metric-thread single nut (ground); MBR = Metric-thread single nut (rolled)
- ② Screw diameter (mm): 04, 06, 08, 10 (example: 06 = 6 mm)
- ③ Lead (mm): 01 = standard 1 mm; 01K = non-standard 1 mm; 02 = 2 mm
- ④ Ball return type: D = Deflector; S = End-deflector; T = Return tube; C = End-cap
- ⑤ Custom option (non-standard)
- ⑥ Threaded section length (mm): decimal point indicated by "_"
- ⑦ Thread direction: R = Right-hand; L = Left-hand; LR = Right- & Left-hand
- ⑧ Total screw length (mm): decimal point indicated by "_"
- ⑨ Accuracy grade: C3, C5, C7, C10 (JIS)
- ⑩ Axial clearance / preload: Z = Preload; T = ≤ 0.005 mm; S = ≤ 0.02 mm; N = ≤ 0.05 mm
- ⑪ Custom serial number
