Our small diameter precision shafts, ranging from 8mm to 200mm, are manufactured to the highest standards of accuracy and surface finish. These shafts are ideal for applications requiring tight tolerances, excellent straightness, and superior wear resistance. Produced from high-grade materials such as carbon steel, alloy steel, and stainless steel, they undergo precision machining and optional heat treatment to meet diverse operational demands. Whether used as guide rods, pivot pins, or transmission components, these shafts deliver reliable performance in compact and high-precision assemblies.

Material Baiting
Rough Turning
Fine Turning
CNC Machining
ID & OD Grinding
Spline Shapping
Gear Shaft Grinding
Material Baiting
BELON tailor the manufacturing process—selecting from Bar Baiting, Tube Baiting or Precision Forging—based on the specific geometry and performance requirements of each gear.
Rough Turning
Rough Turning is the first and fast-cutting stage done on a lathe for gears shape, which is a machining process to rapidly remove the bulk of material from a workpiece, bringing it close to its final shape which is like using a chainsaw to carve a block of wood down to its basic form.
Fine Turning
Fine Turning is a precision finish machining process on a lathe. It is in order to achieve the final dimensions of the finish gears, tight tolerances, and excellent surface finish specified on the engineering drawing which is like using fine sandpaper and a polishing cloth to achieve a smooth, precise final surface.
CNC Machining
CNC machining is a an automated manufacturing process controlled by pre-programmed computer software and code. Normally gears are designed in CAD software. CAM software translates the CAD model into G-Code, a machine language that dictates tools paths, speeds, feeds, and all movements.
ID & OD Grinding
ID grinding, OD grinding, Surface grinding are all belonging to CNC grinding which are the foundational precision abrasive machining processes used to achieve exceptional dimensional accuracy and surface finishes, especially on hardened materials.
Spline Shapping
Gear shaping is a gear cutting process using a reciprocating master gear cutter, and is especially effective for cutting internal gears, including splines.
Gear Shaft Grinding
Gear shaft grinding is the final precision machining operation that refines shaft diameters and surfaces to achieve exact tolerances, superior finish, and perfect geometric alignment.
