Axle Repair

Axle repair and service for silo trailers: BPW, SAF, ROR, Jost. Bearings, hubs, suspension arms, air suspension. Silo trailers, cement tankers. PHS Magnum Chorula, Poland (A4).

In Brief

Axle service covers BPW, SAF, ROR and Jost systems: bearing replacement, hub repair, air suspension, and brake integration. Bearing replacement on one hub: 2–4 hours. Complete axle service: 1 working day. Quotation on request.

A trailer axle carries the full payload weight and transmits braking forces. A 44-tonne loaded silo trailer puts several tonnes through each axle. At these load levels, bearings, hubs and suspension wear faster than on passenger vehicles — and the consequences of failure are proportionately more serious.

PHS Magnum services axle systems on all trailer types, with particular expertise in the axles used in silo trailers and cement tankers (BPW, SAF).

Axle service scope

Wheel bearings — replacement of tapered or fully integrated hub bearings. Diagnosis: thermal camera at the wheels after a run, bearing play measurement. Under normal use bearings last 800,000–1,200,000 km.

Hubs and half-hubs — regeneration or replacement if the thread is damaged or the hub is cracked. Assessment after disassembly.

Seals — oil seal (simmerring) replacement on leaks. Typically done at every bearing replacement.

Drum brakes — during axle service we inspect and service the brakes (linings, drums, cylinders). Brake repair →

Air suspension — air bag replacement, levelling valves, bellows replacement. A worn air bag means the trailer cannot maintain correct ride height and contacts the frame. One bag replacement: 3–5 hours.

Suspension arms and swing arms — for post-collision deformation or material fatigue. Running gear geometry corrected after repair.

When to service the axle

Approximate service intervals:

  • Bearings: every 300,000–500,000 km or on symptoms
  • Seals: at every bearing replacement
  • Brake linings: every 80,000–120,000 km or at thickness < 4 mm
  • Air bags: on leakage or deformation

For intensive operation (heavy loads, urban routes with many stops): reduce intervals by 20–30%.

Frequently Asked Questions

BPW EBC/ECG (standard in Spitzer, Feldbinder), SAF INTEGRAL (Kassbohrer, Schwarzmüller), ROR (older models), Jost (heavy specialist trailers). Bearings, hubs, half-hubs, suspension arms, air suspension, axle studs.

Symptoms: noise at the wheel (humming or knocking — indicates bearing), excessive hub temperature after a run, uneven tyre wear (axle misalignment), detectable play when rocking the wheel, oil leak from the hub (seal failure).

Quotation on request after inspection — cost depends on axle type (BPW/SAF/ROR), number of hubs, and hub condition. Contact us with the trailer make and axle type: +48 602 716 551.

Yes. The TDT inspector checks the technical condition of the running gear during TDT review. Excessive bearing play, hub oil leak or suspension damage can result in rejection or a list of repairs required before the certificate is issued.

Bearing replacement on one hub: 2–4 hours. Complete axle set (3 hubs): 1 working day. Suspension arm or geometry repair: 2–3 days. Depends on corrosion level and parts availability.

Yes. Air bag replacement, levelling valve replacement, hose and fitting replacement. Height adjustment after air bag replacement. Axles: BPW, SAF, ROR.
