polro® two-support kilns, three-support kilns and polguide® drives: parts and repairs for tyres, rollers, thrust systems, gearing and seals.
Current Polysius kilns include polro® two-support and three-support configurations, with polguide® gearing available. ANRANST coordinates Chinese manufacture, quality control and finished-part delivery from the nameplate, serial number, kiln dimensions, support and drive arrangements, installed drawings and worn parts.
Current OEM products and documented historical installations help identify supports, drives, tyres, seals and thrust systems.

High-temperature corrosion, abrasion, contact fatigue, fretting and axial loads require different materials and processes. Confirm each installed position separately.
Refractory Lining & Burning-Zone Lining
Lining protects the shell and establishes burning conditions. Inlet, transition, burning and cooling zones differ in temperature, chemical attack, coating and mechanical loads; confirm zoning, thickness, brick shapes and anchors from lining drawings.
View the common part page →
Kiln Inlet, Outlet & Transition Wear Liner
These protect metal areas at feed and discharge points, the inlet smoke chamber and kiln outlet. Confirm shape, segmentation, holes, overlaps, expansion gaps and refractory interfaces from installed drawings.

Kiln Tyre / Riding Ring Running Surface
Tyres transfer kiln loads to rollers. Inspect diameter, width, section, hot ovality, axial position, contact band, surface damage and load distribution together with the mating rollers.
View the common part page →
Supporting Roller Running Surface
Each station supports a tyre on two roller units. Check roller and shaft diameters, width, contact band, spalling, taper, axes and base elevations as a tyre–roller contact pair.
View the common part page →
Thrust Roller Contact Surface
The thrust roller contacts the tyre side face to control axial position. Confirm roller and shaft diameters, tyre face, contact position, thrust direction, hydraulic stroke and hot axial travel from the thrust-system design.
View the common part page →
Kiln Inlet / Outlet Graphite Seal Blocks
Graphite blocks surround the shell; tension ropes and counterweights maintain contact while allowing axial, radial and wobbling movement. Confirm shape, quantity, gaps, tensioning and air-cooled casing from the seal drawing.
View the common part page →
Tyre Pad, Shim & Axial Stop
These support floating tyres, set clearances and limit axial travel. Confirm curvature, thickness, quantity, weld positions, stop gaps and thermal expansion from installed drawings and measurements.
View the common part page →Check drive and load-bearing spares as assemblies for installed interfaces, loads, materials, heat treatment, NDT, accuracy, lubrication and hot alignment.
Forged Supporting Roller, Axle & Base Unit
The roller and shaft form a permanently joined load-bearing unit; bearings on both sides and the base complete the station. Confirm diameters, width, bearing span, base datums, load and hot alignment before manufacture or repair.
View the common part page →Supporting Roller Bearing, Bush & Housing
Each roller unit has bearings on both sides and a base. Confirm journals, bush bores, oil gaps, bearing area, housing centre height, oil supply and cooling connections from drawings and measurements.
Open the shared bearing and bushing page →Splined / Floating Kiln Tyre Assembly
The assembly includes the tyre and splined connection, or pads, shims, stops and retaining rings. Confirm section, diameter, width, holes, clearances, axial location and hot ovality from the full drawing set.
View the common part page →polguide® Girth Gear, Pinion & Shafting
The self-aligning pinion shaft can move longitudinally; guide rings maintain flank and tip clearances. Check the gears, shafts, bearings, couplings, base and lubrication together.

Hydraulic Axial Thrust System
Located on the downhill side, hydraulic thrust controls kiln axial position. OEM literature gives periodic travel of ±15 mm and short-stroke or combined short- and long-stroke configurations.
Pneumatic / Graphite Kiln Seal Assembly
Seal blocks or leaves, support rings, tensioners, counterweights, air-cooled casing and connectors compensate for axial, radial and wobbling kiln movement.
View the common part page →Drive Gear Unit, Coupling & Lubrication Components
The three-support kiln's electromechanical planetary drive and polguide® gearing require gearboxes, couplings, bearings, brakes, lubrication and monitoring. Confirm nameplate, ratio, torque, shaft ends, base and interlocks from drive drawings.
Open the shared heavy-duty drive page →Tyres, rollers, thrust parts, gears and seals depend on support count, loads, hot ovality, axial travel, centre distances and interfaces. Check nameplate, serial number, assembly and part drawings, and measurements.
First measure both parts for diameter, roundness, taper, contact band and axes. With systematic uneven loading, repairing one part may leave waviness, edge loading or axial wandering unresolved.
