Precision Rollers Series 1800

| Bearings | |
Balls: Precision ground chrome alloy steel Accuracy begins with the shielded deepgroove, chrome alloy, precision- ground ball bearings (ABEC- 1). Cleanliness is insured by an
external "dirtguard" with polyester felt contact seals which protects against contaminants. Axial play is eliminated by the use of bowed retaining rings on both ends of the shaft.
Bearings are housed in a sintered iron housing
produced to extremely "tight" tolerances for concentricity and fit.

Diameters (inch) 2.00, 2.50, 3.00, 3.50 Welded tubing is most cost effective for conveying applications at speeds up to 500 rpm. For high speed applications, drawn- over- mandrel
(DOM) tubing provides better balance and higher strength. Use of DOM tubing is mandated if outside machining is required for crowns, knurls or other machined configurations. In
all cases, tubes are precision end- bored to assure proper housing fit and minimal runout. Typically, tube runout is .030 " TIR; machining the O. D. reduces radial runout to .010"
TIR.

| Shaft | |
Diameter: .669, .787, .984
Hexagonal: .437, .687
Two shafts are available; hex shafts are spring- loaded for typical mounting and are cold drawn steel with bearing seats precision- ground for accurate fit. Shaft ends can be
milled, cross- drilled, tapped or threaded.

| Application | |
Precise in every detail, these rollers are designed for heavy-duty applications requiring high load capacity and long life. These are well suited for high-speed powered
installations where low noise levels are required. Typical applications include parts handling equipment, guided vehicles (AGV's), transfer machines, high speed packaging
lines and belt conveyors.
