A noisy cab, slight vibration on every floor, or premature rail wear often trace back to one overlooked component: the guide-shoe roller.
Nanjing Zhuye Elevator Parts supplies the 200 × 24 × 6203 roller assembly—an industry-standard wheel that keeps elevators gliding quietly and accurately year after year. Below we explain what the numbers mean, how to install and adjust the roller, and the replacement schedule that saves money before emergency downtime strikes.

1. Decoding the Part Number
-
200 mm = outer diameter of the polyurethane tyre
-
24 mm = tread width that contacts the rail
-
6203 = deep-groove ball bearing (17 × 40 × 12 mm) pressed into the centre bore
The combination gives a dynamic load rating of 3.9 kN and a linear speed ceiling of 2.5 m s⁻¹—enough for 1.0–2.5 m s⁻¹ passenger elevators and most freight cars.
2. Where the Roller Sits and What It Does
Installed inside the guide-shoe casing (either T-type or hollow rail), two or three rollers clamp the rail web. While the elevator moves, they:
-
Absorb lateral forces from passenger weight imbalance;
-
Prevent metal-to-metal contact, cutting noise by 8–12 dB;
-
Reduce rail wear, extending rail life by 30–40 %.
In short, they transform sliding friction into low-cost rolling friction.
3. Installation Steps – 15-Minute Swap
Safety first: engage the elevator on “INSPECTION” and lock the cab with safety props.
Step 1 – Remove the old roller: take off the M12 shoulder bolt, slide the worn roller out, and clean the shoe cavity.
Step 2 – Inspect the axle; if scoring > 0.2 mm, replace or polish with 600-grit emery cloth.
Step 3 – Hand-press the new 200 × 24 × 6203 roller until the bearing seats flush.
Step 4 – Re-insert the shoulder bolt with medium-strength thread locker.
Step 5 – Adjust eccentric cam until the roller kisses the rail with 0.05–0.10 mm preload (use feeler gauge).
Step 6 – Spin by hand—smooth rotation, no lateral play.
Step 7 – Run on inspection speed for three full cycles, then torque all bolts to 55 N m.
Step 2 – Inspect the axle; if scoring > 0.2 mm, replace or polish with 600-grit emery cloth.
Step 3 – Hand-press the new 200 × 24 × 6203 roller until the bearing seats flush.
Step 4 – Re-insert the shoulder bolt with medium-strength thread locker.
Step 5 – Adjust eccentric cam until the roller kisses the rail with 0.05–0.10 mm preload (use feeler gauge).
Step 6 – Spin by hand—smooth rotation, no lateral play.
Step 7 – Run on inspection speed for three full cycles, then torque all bolts to 55 N m.
No grease nipple is needed; the 6203 bearing is packed for life with Chevron SRI-2 grease (-30 °C to 150 °C).
4. Maintenance & Replacement Cycle
High-rise office (>1 000 starts/day) – inspect every 3 months, replace roller every 18 months.
Residential tower (300–600 starts/day) – inspect every 6 months, replace every 3 years.
Low-rise freight (≤200 starts/day) – inspect annually, replace every 5 years.
Residential tower (300–600 starts/day) – inspect every 6 months, replace every 3 years.
Low-rise freight (≤200 starts/day) – inspect annually, replace every 5 years.
Replace earlier if:
-
Tread diameter falls below 194 mm (3 % wear);
-
Polyurethane shows radial cracks > 2 mm depth;
-
Bearing emits > 75 dB(A) at 1 m or temperature exceeds 65 °C;
-
Roller wobble exceeds 0.3 mm when 50 N side-load is applied.
5. Prolonging Life – Three Tips from Nanjing Zhuye
-
Keep rail straightness ≤ 0.5 mm / 5 m; kinked rails eat rollers.
-
Clean rail heads monthly; brake-dust paste acts like grinding paste.
-
Align car and counter-weight shoes on the same rail axis; misalignment doubles roller wear.
