Polyurethane vice jaws with cross-serrated gripping surfaces provide maximum grip while still offering some surface protection — the polyurethane material is softer than steel, reducing marking, but the cross-serrations provide aggressive engagement that resists workpiece slippage even under heavy loads. The Sykes Pickavant 53341500 Poly-U Jaws are 150mm-wide insert jaws with cross-serrated faces, designed to fit the Sykes Pickavant 150mm vice.
The cross-serrated pattern is the defining feature — each jaw face is machined with a grid of small ridges that bite into the workpiece surface, providing significantly more grip than smooth-faced inserts. This makes cross-serrated polyurethane jaws the right choice for high-grip applications where rubber, fibre, or smooth-poly jaws would slip.
The polyurethane material adds a degree of surface protection compared with serrated steel jaws — the softer face deforms slightly under pressure rather than cutting into the workpiece, leaving a less aggressive imprint than equivalent steel serrations. For workpieces that can tolerate some surface marking but cannot accept the cuts that hardened steel serrations would leave, polyurethane is the appropriate compromise.
The 150mm width matches the Sykes Pickavant 150mm vice format. Within the wider Sykes Pickavant vice jaw insert range, polyurethane jaws are also available with grooved profiles (53351500 in 180mm with grooves) for different gripping characteristics, alongside rubber-covered, fibre-covered, and prism/vee inserts for other workpiece types.
Sykes Pickavant has been supplying professional vice and bench equipment for decades, and the polyurethane jaw range reflects the brand's modular approach to vice configuration where high grip is required without the marking risk of steel jaws.
Additional Information
- 150mm Polyurethane Cross Serrated Magnetic Jaws compatible with any 6" Vice including the Sykes-Pickavant Unbreakable Vice.Polyurethane with small cross serrations for a firm grip with a shore hardness of A82. "Bites onto" the work piece without damaging or scratching it and is is so flexible, that it returns to its original shape after deformation.
- Equipped with an extremely powerful magnetic strip which easily attaches the jaw to the vice and ensures a rapid setup.
- The magnetic strip is only magnetic against the vice jaws and will not attract debris or fillings to the clamping surface nor magnetize the clamped parts.
- Features an extremely powerful neodymium magnetic strip. Holding force for a 100mm jaw is 3.5kg equivalent to 34N, for instance.
- These Magnetic Jaws can also be used in combination with one another. For instance, for taper pins or thin walled tubes use the Neutral or Prism / Vee Pipe together with the Rubber option. For irregularly profiled parts with one flat surface use the Fibre covered on the flat surface and the rubber covered on the profiled side.
