Premium Dorma Track Wheels: ES200 Carriage Wheel Assembly

Looking for reliable dorma track wheels? The Dorma ES200 carriages, hang wheels, sliding door trolleys or door connections, are precision-engineered components fixed on door panels or door wings as connections to the track rail profile. For frameless sliding glass doors or french doors, a glass clamp is required to joint the glass panel and trolleys. (This carriage is fully compatible with the Dorma ES200 system).

Typically, there are 4 pieces of carriage in a standard pack of Dorma ES200, each moving wing of the door needs 2 pcs.

• Bi-parting sliding doors or double sliding doors – 4 pcs (left x 2pcs, right x 2pcs)
• Single sliding doors – 2 pcs (left x 1pc, right x 1pc)

Technical Specifications

• Model / Part Name: Dorma ES200 / ES200e Carriage Wheel Assembly (also known as Dorma Carrier, ES200 Carriers, Carriage/Hang Wheel).
• OEM Part Number: 9925518001150
• System Compatibility: Designed for the Dorma ES200 operator family; widely used on "Standard", 2D, and EASY/ES200e variants.
• Function: Precision trolley that links each sliding door leaf to the track rail. Functioning as high-performance dorma track wheels, the assembly uses two load-bearing dorma rollers plus a smaller anti-riser (anti-jump) guide wheel and provides height/level adjustment via an eccentric wheel.
• Quantity per Door: Two carriers per moving leaf (left + right). A bi-parting entrance uses four carriers total.
• Operator Weight Context:
  • Dorma ES200 Standard: up to 1 x 200 kg or 2 × 160 kg.
  • Dorma ES200-2D: 1 × 150 kg or 2 × 130 kg.
  • Dorma ES200 EASY: 2 × 100 kg.
• Door Types: Compatible with framed aluminum leaves or frameless glass when paired with the appropriate glass clamp between glass and trolley.
• Typical Kit: Left and right carriers supplied; standard Dorma ES200 sets use 4 pcs for two-leaf doors.

Professional Product Overview

The Carriage Wheel Assembly, often called the Dorma Carrier, is the precision trolley responsible for suspending each door leaf on the Dorma ES200 track and delivering smooth, quiet travel in demanding commercial environments. In every opening, these heavy-duty dorma track wheels do the heavy lifting: they bear the door load, maintain alignment with an anti-riser guide wheel, and provide millimetric height adjustment through an eccentric mechanism to fine-tune clearances and sightlines.

Compatibility You Can Trust

Dorma ES200 is one of the most widely deployed automatic sliding door platforms, supported across standard, escape-route, and cost-optimized variants. This carrier assembly is designed for fitting rails and door connections perfectly. In practice, that means straightforward hang-and-adjust service calls whether you’re replacing worn dorma rollers in a retail storefront or re-commissioning a hospital corridor entrance after glazing work.

Performance Aligned to the Operator

The correct Carriage Wheel Assembly is essential for meeting the operator’s certified weight limits and duty cycle. Matching carriers to the operator class keeps the rolling resistance low, reduces rail wear, and preserves stop-to-stop travel accuracy—especially important for Partial Open and Night/Bank modes where repeatable positioning is critical.

Dual-Roller Stability with Anti-Rise Control

Each Dorma ES200 Carrier pairs two primary dorma rollers with an anti-rise guide wheel. The anti-riser prevents uplift under transient loads (like wind gusts or an off-center push). The eccentric on the main dorma roller axis offers predictable, repeatable height adjustment so you can set reveals, minimize mullion clash, and achieve silent travel along the profile.

Why Specifiers Choose this Assembly

Ecosystem Continuity: Dorma ES200 has been the backbone of countless storefront and institutional entrances for years. Using a carrier matched to the OEM geometry (Part Number 9925518001150) protects the investment in rails, end stops, and safety peripherals while ensuring parts availability worldwide.

Compliance Ready: These platforms are engineered to the European DIN 18650 and EN 16005 safety frameworks for automatic doors. A properly adjusted carrier helps the operator achieve the monitored forces and edge safeguarding those standards expect.

Installation Tips for a Perfect Glide

• Pre-load check: Before hanging, roll each carrier by hand; any roughness indicates bearing wear—replace instead of reinstalling.
• Level first, then seal: Use the eccentric to set the reveal and head seal clearance; only then set the floor guide and bottom seals so you don’t “chase” friction later.
• Anti-riser clearance: Set it to just clear the rail across the full stroke; contact causes noise and accelerates wear.
• Glass clamp torque: On frameless doors, always follow the clamp manufacturer’s torque and gasket guidance to avoid slippage or glass edge stress.

Frequently Asked Questions (FAQ)

Q1. Is this set of dorma track wheels fully compatible with Dorma ES200 / EASY?

A. Yes. This carrier style is built for Dorma ES200 family rails and door connections and is commonly specified for Standard, 2D, and EASY installations.

Q2. How many Dorma ES200 Carriers do I need per door?

A. Use two per moving leaf (one left, one right). Bi-parting doors therefore require four carriers total.

Q3. What does the small middle wheel do?

A. That is the anti-riser guide wheel. Together with the carrier’s eccentric wheel, it lets you level the leaf and prevents uplift. After adjustment, the anti-riser should not contact the top track along the travel path.

Q4. What door weights does this support?

A. Follow the operator’s certified limits: Dorma ES200 up to 1 x 200 kg or 2 × 160 kg; 2D variant up to 1 × 150 kg (and often 2 × 130 kg bi-parting); EASY variant up to 2 × 100 kg.

Q5. I’m hanging frameless glass. Do I need anything else?

A. Yes—use rated glass clamps between each glass leaf and trolley to join the panel to the rail profile safely.

Q6. How do I level the door after hanging it on the Carriage Wheel Assembly?

A. Adjust height/level via the eccentric dorma roller wheel and set the anti-riser so it clears the rail at all positions. Then securely tighten the lock-nuts.
