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.\u003c\/p\u003e\n\u003cp\u003eThe 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\u003eThe Stand-Up Orbit Blocks are supplied with stainless steel padeyes and rubber support bases.\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.
