803303171 VD300A Seal Ring — JB/T6994-2007 VD-Shape Rubber Rotary Shaft Seal, 270×300×25mm

This is a VD-shape rubber seal ring​ (Part No. 803303171, type VD300A) manufactured to JB/T6994-2007​ "VD shape rubber seal ring" standard . The "VD" profile is a thickened-lip V-type rotary seal used for face sealing and dust-proofing​ on rotating shafts . VD300A corresponds to nominal shaft diameter 300 mm:

  • Inner diameter d: 270 mm

  • Nominal shaft / outer diameter D: 300 mm

  • Section thickness C: 15 mm

  • Free width A: 15 mm; B: 14.3 mm

  • Installed width B1: 25 mm (25±4 per table)

  • Shaft range: Ø290–310 mm

LW700HV, LW700KV, LW800K, LW800KV, LW800KN, LW900KN, LW1000KN, LW1200KN​ .

In available BOM data it appears inside a cylinder/body assembly​ together with cylinder body, piston, piston rod, retaining rings, Glyd ring (90×74.5×6.3), O-rings, Step seal (40×55×6.3), shaft seal, guide sleeve and wiper — i.e. it is one of the sealing elements of that assembly at the Φ300-class shaft/seat​ position . Because the same part number can appear in multiple sub-assemblies across the listed models, confirm the exact installation point from the old seal or the machine's disassembly drawing​ before ordering.
