CNC Nylon Rack Plastic MC901 Gear Rack | Sliding Gate OEM Supply
Ever-Power CNC nylon rack MC901 gear racks are manufactured from 100% virgin MC901 nylon raw material using CNC machining — nonstandard dimensions to your drawing, available in natural and blue colour, with density 1.2 g/cm3 and thickness from 5 mm to 250 mm. MC901 is the highest-grade cast nylon available, with outstanding toughness at low temperature, high surface hardness, good impact and notch impact strength, high heat deflection temperature, excellent glide and self-lubrication, and chemical stability against organic solvents and fuels. Operating temperature range -50C to +110C. ISO 9001:2015 certified; test report with every order.
CNC MC901 Nylon Gear Rack for Sliding Gate — Overview
Ever-Power CNC MC901 nylon gear racks are manufactured from 100% virgin MC901 monomer-cast nylon using CNC precision machining. MC901 is the highest-molecular-weight grade of cast nylon commercially available in machinable bar and plate stock — it delivers properties that standard extruded PA6 and PA66 cannot match in tooth hardness, impact resistance, and fatigue life. The combination of virgin raw material (no recycled content) and CNC machining ensures consistent tooth geometry, density, and mechanical properties batch to batch, which is essential for sliding gate operator drives that must perform reliably for 10-15 years in outdoor conditions without rack replacement.
All dimensions are nonstandard — every rack is CNC-machined to your drawing specification, covering thicknesses from 5 mm to 250 mm and any module, length, hole pattern, or cross-section required. The natural and blue colour options reflect the two most common MC901 grades: natural (off-white) for standard mechanical applications, and blue (oil-impregnated MC901 blue) for drives requiring extended self-lubricating life at higher load or lower speed.

MC901 Nylon Properties — Why 100% Virgin Material Matters
MC901 nylon made from 100% virgin raw material delivers the following properties. Each is listed with its specific benefit in gear rack applications where sliding gate drives must perform reliably at both low winter temperatures and high summer temperatures throughout the expected service life.
| MC901 Property | Performance Level | Benefit in Rack Applications |
|---|---|---|
| Tensile strength | 80-100 MPa | Higher tooth load capacity vs standard PA6/PA66 |
| Impact strength (notched) | 8-14 kJ/m² | Absorbs shock loads without tooth fracture |
| Heat deflection temp. | Up to 110°C | Suitable for drives near motors or in warm enclosures |
| Surface hardness | High (Shore D 75+) | Resists tooth surface wear at high cycle count |
| Glide / self-lubrication | Excellent | Eliminates lubricant maintenance schedule |
| Chemical stability | Good vs solvents / fuels | Suitable for agricultural and chemical plant environments |
| Thermal aging resistance | -50°C to +110°C | Operates reliably through seasonal temperature cycles |
| Humidity consideration | Moisture causes dimension change | Allow 0.2-0.3% length growth at equilibrium humidity |
Applications
🏙 Sliding Gate Drives
MC901 nylon racks for residential and commercial sliding gate operator systems. The 100% virgin raw material construction ensures consistent tooth geometry and density — critical for smooth, quiet mesh with the gate motor pinion across the full temperature range from winter frost to summer heat. Module M4 standard; M6 for heavy-duty commercial gates.
⚙ Mechanical Equipment — Wear Parts
MC901 is widely used to replace wearing parts in mechanical equipment, and to replace copper and alloy components as wear elements — including shaft sleeves, bearing bushes, bushings, lining plates, worm gears, roller guide rails, piston rings, sealing rings, and sliders. The same material properties that benefit gear rack drives also benefit these adjacent applications.
🏭 Industrial Components
Ball bowls, impellers, vanes, cams, nuts, valve plates, pipes, stuffing boxes, racks, pulleys, and pump rotors are all standard MC901 applications alongside gear racks. This breadth of application reflects MC901 nylon versatility — one polymer grade covering a wide range of mechanical engineering needs in a single production facility.

Material of Plastic Gear Rack
Plastic racks can be made from a variety of materials. The traditional PR series uses MC nylon, while the PRF series adds end machining to connect multiple sections for long-travel drives. The polyacetal-based DRFD and DRFK series include mounting holes. The injection-moulded DR series has unique flexibility properties suitable for curved-path locations. The material selected depends on the daily cycle count, the required force, and the environment — moisture, chemical exposure, and temperature. Dimensional stability is critical for maintaining gear tooth contact ratio, tooth tip clearance, and overall geometry throughout the service life.
Quality Assurance and Manufacturing
Ever-Power MC901 nylon gear racks are produced under ISO 9001:2015 quality management. All bar stock is verified as 100% virgin MC901 material by density and hardness measurement before entering CNC production. Tooth geometry, pitch, cross-section dimensions, and thickness are inspected on every batch. A test report covering material specification, dimensional inspection results, and batch reference is supplied with every order.

Frequently Asked Questions
Why must MC901 nylon be made from 100% virgin raw material?
Recycled or regrind nylon has lower and less consistent molecular weight than virgin material — the recycling process breaks polymer chains, reducing the impact strength, tensile strength, and wear resistance that are the key advantages of MC901. For a gear rack application where consistent tooth strength and fatigue life across every batch are required, 100% virgin MC901 is the correct specification. Ever-Power does not use recycled nylon content in MC901 gear rack production.
What does the thickness range 5-250 mm refer to for a gear rack?
The thickness dimension for a flat gear rack refers to the height of the rack body measured perpendicular to the tooth face — i.e., from the mounting back face to the tooth tip. This dimension determines the bending stiffness of the rack under tangential tooth load and the section modulus available to resist bending at mid-span. For sliding gate drives the required thickness is typically 15-30 mm; for heavy industrial drives or long unsupported spans the thickness may be 50-100 mm or more. The 5-250 mm range reflects the full CNC machining capability from thin guide racks to large structural components.
How does the operating temperature range of -50°C to +110°C affect installation?
MC901 nylon retains good impact strength and toughness down to -50°C — the polymer does not become brittle at the low temperatures experienced in outdoor winter gate installations in northern climates. At the upper end, the 110°C heat deflection temperature means the rack can be used adjacent to drive motors or in warm enclosures without softening or creep under sustained tooth load. However, nylon expands with temperature — a 1,000 mm MC901 rack grows approximately 1.5 mm from -20°C to +40°C — so a thermal expansion gap of 0.5-1.0 mm should be left at each section butt joint.
