MANHELF spare parts catalog

Initially, MANHELF focused on components where errors were unacceptable: steering and hydraulics.
Over time, the line grew into a comprehensive portfolio of key components that impact vehicle reliability on a daily basis:

Power steering pumps

A reliable power steering system means a confident ride. Our pumps maintain consistent steering support and help reduce wear on the entire system. MANHELF power steering pumps are designed with a focus on durability and predictable flow: we maintain channel geometry, monitor clearances between power steering components, and test each component under conditions similar to real-world use.

High-precision mechanics

Grinding and finishing of working surfaces ensure stable flow and minimal leakage within the operating range.
Reduction of noise and vibration

Rotor balancing and fluid path optimization help reduce cavitation and maintain quiet operation.
100% control at the stand

Each pump is tested for pressure, performance, tightness, and noise, with results recorded per batch.
Materials and protection

The housings and covers are made of highly corrosion-resistant alloys; the shafts and bushings are heat-treated and coated with protective coatings.
Stable pressure

The design is calculated to ensure repeatable performance at different temperatures and conditions - from city traffic jams to highway driving.
Ready to install

OEM-compatible mounting dimensions, correct markings, and completeness reduce the risk of errors during service.

Steering racks

MANHELF places special emphasis on the consistent performance of its steering racks, including precision, smoothness, and durability. Each rack is assembled on high-precision test benches, and key components undergo 100% final performance testing.

Wear resistance

Rods and shafts made of 40Cr/45Cr alloy steel family provide high strength and fatigue resistance.
Tightness

Seals and gaskets made from synthetic NBR retain elasticity and reduce the risk of leaks.
Working pressures

The designs are designed for hydraulic system ranges: high circuit 70-140 bar and low 5-10 bar (depending on the design).
Uniformity of effort

The bearing units are designed for stable operation; the hardness of the rolling elements is brought to a level of approximately HRC 58-60.
Bench tests

Each rack undergoes output parameter testing: force, smoothness, noise, and tightness.
Electric power steering

Modules and control units are tested separately to eliminate problems during installation and connection.

Filters

Maximum protection in real-world conditions. Dust, traffic jams, temperature fluctuations—our filters withstand impact and help extend the life of your engine.

Paper and synthetics

For air filters, we provide high
air permeability - up to 800 m³/(m² h) depending on the type of element.
Modern compositions

We use nanofibers, combinations of cellulose and
synthetic fibers, as well as absorbent additives to capture contaminants.
Low resistance

Optimized fold geometry reduces losses to less than 0.03 kPa over the operating range.
Pressure resistance

The oil filter material can withstand
pressure of approximately 600 kPa while maintaining its fiber structure.
Efficiency

Up to 98% for particles around 4 µm and up to 99% for 6 µm (depending on the model).
Reliability of the housing and seals

The housing strength is up to 3Pnom, the seals hold up to 2.5Pnom, helping to eliminate suction and bypass.

AIR SUSPENSION

Comfort and control in any conditions.
Potholes, overloads, uneven roads—MANHELF air suspension helps maintain a smooth ride, vehicle stability, and driving confidence on every journey.
