A Börkey Roller is available in many variations as every Börkey Roller can be built to best match a specific application. Starting with a base roller construction, each component can be upgraded to improve durability, reliability and functionality. The highest possible quality may certainly be required when moving a nuclear reactor, but not every application calls for the most expensive roller configuration as each component upgrade increases the cost.
It is important to remember that the roller selection should always exceed the application requirements for safety and usability, however, consider selecting a cost-effective roller configuration that makes economic sense in relation to the application. Hence Börkey has created different levels of quality to suit different application requirements.
The graphic below provides a clear understanding of each quality aspect of a roller and will show which features – including component upgrades and construction methods – are included on which roller models.
Generic Competitors (Lower Quality)
|Low cost cast iron one piece frame is brittle and less dependable.|
|2/10||A welded-in center plate has weaker joints prone to shearing and is far less dependable.|
|3/10||Their basic wheels are likely to crack and deform.|
Börkey Rollers (Higher Quality)
Standard DutyCarbon steel interlocking frame construction with pass-through center plate.
|5/10||Our hardened roller wheels have higher durability (against point-loading) and toughness.|
Heavy DutyA hardened center plate provides easy rolling after long standstills under load.
|7/10||A reinforced design provide additional frame strength against twisting.|
Super DutyOur super duty roller wheels (50CrV4 steel) provide high safety capacity against point loading (rocking) and side forces (wind).
|9/10||A channel chain guide keeps rollers on 360° track preventing roller chain damage.|
Ultra DutyA center chain guide provides superior 360° chain guidance for frequent use.
|Access holes allow for repair of chain while under load. Available on request for selected models only.|
