MBG · MBR Metric Thread Single Nut

Part Number Construction
Example: MBG 06 01 D X - 60 R 90 C3 Z - 001

• ① Series: MBG = Metric threaded single nut (ground); MBR = Metric threaded single nut (rolled)
• ② Screw Diameter (mm): e.g. 06 = 6 mm (available: 04, 06, 08, 10)
• ③ Lead (mm): 01 = Standard lead 1 mm; 01K = Non-standard lead 1 mm
• ④ Ball Return Type:
  • D = Deflector type
  • S = End deflector type
  • T = Return tube type
  • C = End-cap type
• ⑤ Custom Option (non-standard): reserved position for custom code
• 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 = JIS C3; C5 = JIS C5; C7 = JIS C7; C10 = JIS C10
• ⑩ Axial Clearance: Z = Preload; T = ≤ 0.005 mm; S = ≤ 0.02 mm; N = ≤ 0.05 mm
• ⑪ Custom Serial Number: customer-specific serial
