Side cheeks incorporating head structure and hub are precision machined as a single part from solid alloy, leaving material only where it contributes to the load carrying capacity of the block and eliminating the need for additional fasteners. The Orbit sheave has captive acetal or Torlon ball bearings for side thrust loads, eliminating the need for side retainer plates. This reduces weight and allows for a wider bearing surface that can accommodate longer Torlon needles – achieving a substantially higher strength-to-weight ratio.\u003c\/p\u003e\n\u003cp\u003eHead posts of swivel blocks can be locked at 0 or 90 degrees.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eThe highest strength-to-weight ratio.\u003c\/li\u003e\n\u003cli\u003eMinimal friction loss, especially when working at high loads.\u003c\/li\u003e\n\u003cli\u003eCaptive ball bearings for side thrust loads.\u003c\/li\u003e\n\u003cli\u003eTotally reliable and trouble free performance.\u003c\/li\u003e\n\u003cli\u003eSimplicity of design and construction to facilitate maintenance and servicing.\u003c\/li\u003e\n\u003cli\u003eElegant, functional styling and finish.Lockable swivelling head post.\u003c\/li\u003e\n\u003cli\u003eHigh strength forged shackle\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eSpecification:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eMax.
