Safety, reliability and affordability are the main requirements for a locking door device for customers. The cylinder mechanism, due to its simplicity and versatility, is successfully used by many manufacturers and is found on the market in a large assortment and various modifications.

Types and forms

Different types and methods of installation make the cylinder lock universal, the selection of the type is carried out depending on the material of the leaf and the requirements for the operation and appearance of the door.

The cylinder mechanism has a standardized size, making it easy and quick to replace.

The shape is a cylinder, but there are also round, drop-shaped or triangular designs.

Types of cylinder mechanisms: disc, pin, frame, magnetic or special with increased complexity.

Installation method:

• Mortise. Installed in a hole madeinside the case, if the leaf is solid, or in the case of a hollow metal door, it is embedded in a special box, followed by a front finish.
• Invoice. Installation is carried out directly on the outer part of the door.

Building

The cylinder mechanism for the lock consists of two main parts: cylinder and executive. Designed to move and fix door locks, the reliability of the entire system is ensured by the design feature of the secret mechanism.

Castle building:

• The shell is most often made of brass, the mechanism is installed in it. The thicker the wall, the less likely it is to get to the filling from the outside of the door.
• Locking mechanism.
• Bolts (bolts) - fixing elements. In the closed position, they go into a special locking hole in the door frame. The quantity depends on the model and its degree of reliability.
• Bolt (latch) - an element that helps keep the door in the closed position, enters the door frame body through the striker.
• Lever - ensures the operation of the mechanism when locking / unlocking.
• The front face plate of the mortise lock is a fastening element that also has a decorative function.
• Strike plate - installed on the door frame, has holes for bolts.
• Key is an element that starts the system.

Working principle

The operation of the system is simple, a key or a turntable latch rotates the tongue of the cylinder mechanism (lever), which startsdeadbolt work. Only the width of the mechanism has a standard size, the length is selected depending on the thickness of the door.

The cylinder mechanism for the lock is classified according to the method of opening:

• The key works only from the outside, a rotary handle is provided on the back side - one-sided type.
• Key holes on both sides of the door - double sided type. The key/key cylinder mechanism is most often made of aluminum with a protective brass insert. Used for mortise types of locks.

Mechanism actuation

Any lock produced or imported into Russia must have accompanying documentation - a certificate of conformity and comply with GOST requirements.

When choosing a cylinder mechanism for a lock, it is necessary to pay attention to its class, which depends on the response time (the number of cycles to be worked out).

Operation cycles

Class	I	II	III	IV
Minimum number of thousands of cycles to lock the cylinder mechanism	80	90	100	120

To increase the protection of the lock cylinder, many manufacturers: thicken the wall of the case, increase the number of structural elements of the mechanism. Materials used: hardened, alloyed metals, as well as compositeitems.

Hack protection

Reliability of burglar resistance depends on the class (I-IV) and is characterized by the time (min) required to destroy the main elements of the lock:

• Drilling a lock/secret mechanism for I-IV class: 2; 5; fifteen; 30 minutes.
• Twisting the contents of the cylinder, for II-IV class: 50, 100, 250 Nm.
• Mechanical impact loads, for class II-IV: 80, 150, 300 J.

The cylinder mechanism has a secret of varying complexity, depending on the number of combinations created by the pins. The length of the locking pin is the same, unlike the code ones. The number of combinations (N) and complexity is determined by the number of notches n and notches k on the working surface of the key, total: N=n^k

Kale locks: lineup, key features

Kale locks are a worthy member of the cylinder family and are widely sought after and respected by door manufacturers and many customers. The resource of the locks of this company is designed for at least 40 thousand cycles, which greatly increases the service life and minimizes the number of failures.

Maximum protection against hacking: the possibility of recoding, the presence of an armor plate, the system of blocking pins OBS - when trying to hack (bumping), mushroom-shaped pins - protection when selecting a code; rods made of high quality alloy steel - from drilling.

Kale locks (cylinder mechanism "Series 164"):

• BNE-Z (IV class). For metaldoors, 2 mounting keys, maximum protection against burglary. Protection against drilling, bumping, picking, code selection.
• AS (Grade IV). Alarm operation, 6 brass pins, basic burglary protection methods.
• CEC (IV class). Additional steel insert, OBS protection, code elements in 3 rows, reversible key.
• YGZ (Grade IV). Steel insert through cylinder body, OBS system, 6 brass combination pins.
• DB (IV class). 10 combination brass pins, OBS system, additional steel plates. Model DBME (wrench) - increased tear resistance.
• OBS B. 10 combination pins made of brass, OBS S – 6 pcs., safety class IV, blocking pins operating according to the OBS B and OBS S system, respectively. Models OBS BN and OBS S - key/key cylinder mechanism; BC and SC key combination with turntable.
• B (Class II): 10 combination pins. DBME-break protection key/revolver, BN key/key, BM key/revolver.
• S (Class II): 6 combination pins (91,000 combinations). SX - long stem, SN key/key.
• G (Class II): 6 combination pins (55,000 options) GN - key/key, GM key/revolver.
• F (Grade II): made to open with a cross-core key, 6 brass pins.

Apecs cylinder mechanism: types, characteristics

Apecs has been the largest distributor of locks and various door fittings on the market of the former USSR since 1992.

Most popular amongbuyers use cylinder mechanisms, despite the wide price range, any product offered is of high quality and excellent design.

The company offers two types of cylinder systems:

• Symmetrical.
• Asymmetrical.

Stamps:

• XS. Pins 18; steel pin pressed into the cylinder body - protection against drilling; steel plate - tear protection; two steel clamps of the cylinder body - protection against attempts to pull the core; duplicate only from the original.
• SC: eurocylinder, key type SC-Z-C English, for Blister - profile key. Brass cylinder, 6 pins. Two kinds: with pinwheel and lock/lock.
• XD IV grade. Bump protection. Mechanism length: 62 mm - 11 pins and for 72 mm - 13 pieces. Double-row arrangement of pins. Two pins are made of high strength steel. Steel insert against tearing, anti-knockout protection. Special grooved pins.

And finally

Choosing a lock is a task that requires an individual approach in each individual case. The cylinder mechanism for the lock has been popular among buyers for more than a dozen years, and a wide variety allows it to be used both in ordinary interior doors,serving only as a dividing barrier, and for entrance doors, providing them with the maximum level of protection.
